With Mark Schlabach's most recent Way-Too-Early Top 25 rankings as our guide, we have ranked everything from the weakest position groups to the most likely future presidential candidates.

This week, football meets Hollywood. Who are the top celebrity fans for the top 25 teams?

Melissa Joan Hart

Her husband introduced her to Alabama football, and Hart took it from there. Now the actress gobbles up everything Tide-related, and she follows beat writers and recruiting prospects alike on Twitter. -- Alex Scarborough

Rex Ryan

The always effusive head coach of the Buffalo Bills rarely hides an opinion, and that goes for his new favorite college football team. Ryan, whose son, Seth, is a junior wideout for Clemson, has become an outspoken fan of the Tigers the past few years. He routinely shows up to news conferences and public events wearing the orange and purple. -- David M. Hale

Kate Upton

The Wolverines can count several famous people as fans, including Madonna, Russell Crowe, Michael Phelps and, of course, former player Tom Brady. But you'd be hard-pressed to find a bigger name than that of supermodel Kate Upton. The Michigan native has been seen wearing the maize and blue for years. -- Brian Bennett

Roy Jones Jr.

The Seminoles claim Bandit and Sunshine Scooter among their constituency, but both Burt Reynolds and Lee Corso played at Florida State (and were roommates). The King said he roots for FSU, but LeBron James is synonymous with Ohio (and is often seen in Buckeyes garb). Jones is a Pensacola, Florida, native and a big FSU fan. He has been seen at football practices, and the top-50 boxer has even written a rap song for FSU basketball. -- Jared Shanker

Toby Keith

Seeing Keith roaming the sidelines at the University of Oklahoma is a common sight. The country music star is a big fan of Sooners athletics and Oklahoma football in particular. But, ironically, his song "Should've Been A Cowboy" is played often at Bedlam rival Oklahoma State's games. -- Brandon Chatmon

Tim McGraw

Several celebrity Tiger fans come to mind: rapper Lil Wayne, the Robertsons of "Duck Dynasty" and political consultant James Carville, for starters. But let's go with country music superstar McGraw. The native Louisianian wears his purple and gold heart on his sleeve and narrated the ESPN SEC Storied film "Shaq & Dale" about the special relationship between former LSU basketball coach Dale Brown and star player Shaquille O'Neal. -- David Ching

Condoleezza Rice

The Cardinal have a few celebrities to choose from. Golfers Tiger Woods and Michelle Wie both went to the school and frequently attend football games. Rob Lowe's son is currently a student at Stanford, so the actor has been spotted wearing Cardinal gear at games. Former Secretary of State Condoleezza Rice, of course, is on the faculty at Stanford and an avid football fan. For that reason, she must recuse herself from discussion of the Cardinal whenever they come up at a College Football Playoff ranking meeting. -- David Lombardi

Vince Vaughn

Vaughn gets the nod here, as the Chicago native has been on the Irish sidelines, on "College GameDay" and at games in a number of films, most notably "Rudy." He's hardly alone, however; rock star Jon Bon Jovi was a regular at games even before his son, current Irish corner Jesse Bongiovi, joined the team. -- Matt Fortuna

LeBron James

James has been a frequent attendee of Buckeyes football games, and he stood on the sidelines as Ohio State beat Oregon in the 2015 national title game. The Buckeyes have returned the love to the NBA superstar, as Urban Meyer has attended Cleveland Cavaliers playoff games, and Ohio State leaders reveled in last week's championship parade for the Cavs. James has a locker in the Ohio State basketball complex, even though he skipped college to go straight to the NBA. -- Bennett

Kenny Chesney & Lil Jon

Country music star Kenny Chesney likes to give his heart to many in the sport (see: Steve Spurrier and Tim Tebow), but the Knoxville native's heart lies with Tennessee football. He isn't shy about his fandom, and he's a regular at Tennessee games. Rapper Lil Jon is loved by just about everyone, but Tennessee took its love for East Side Boyz front man with its infamous "Third Down For What" call during games, which is a play off of Lil Jon's recent club banger "Turn Down For What." Lil Jon has now pledged some allegiance to the Vols, as has rap group Migos, which running back and Atlanta native Alvin Kamara has befriended. -- Edward Aschoff

Will Ferrell

Ferrell attended USC, and he has stayed active with the football program well into his time as an A-list celebrity. During the glory days of the Pete Carroll era, Ferrell was known to assist the coach in pranks at the end of practice to help keep the mood light around the program. Ferrell can still be found on the sidelines at the Coliseum -- or even in Tommy Trojan garb as the leader of USC's famous marching band. -- Lombardi

Ryan Seacrest

The University has had its fair share of famous alumni. There are Newman from "Seinfield" (Wayne Knight), PGA star Bubba Watson, Inside the NBA host Ernie Johnson and Aaron Murray's brother, Josh Murray, who won "The Bachelorette," so that's something. But we have to go with entertainment mogul Ryan Seacrest, who fell short of his degree by bolting to Hollywood. Anyone who knows anything about Hollywood knows Seacrest, who first garnered fame as a host on "American Idol." He has created and produced shows such as the uber-popular "Keeping Up With the Kardashians." Acclaimed hip-hop great Andre 3000 of Outkast is a huge Bulldogs fan, as is fellow hip-hop star Ludacris, whose now-infamous spring-game requests will go down in football-celebrity lore. -- Aschoff

Katy Perry

Alum Shepard Smith left school early to pursue his career in journalism, but Ole Miss has no problem claiming the Fox news host as its own. Smith started with Fox News during its inception in 1996 and currently serves as the chief news anchor and managing editor of Fox News' breaking news division. NASCAR couple Danica Patrick and Ricky Stenhouse Jr. have become mega Ole Miss fans, as has pop star Perry, who famous mocked LSU fans by tossing corndogs on the set of ESPN's College GameDay and danced her way through the Square and into the Grove before the 2014 Alabama game. Academy Award-winning actor Morgan Freeman is also no stranger to Ole Miss' campus. -- Aschoff

Garth Brooks

Not only is Brooks an Oklahoma State fan, but also he once wore an Oklahoma State uniform as a javelin thrower after earning a track scholarship to the school. The country music star was inducted into Oklahoma State's Alumni Hall of Fame alongside Barry Sanders and Robin Ventura in 2009. -- Chatmon

Magic Johnson

Although he is clearly more associated with the school's basketball program, the former Spartans great and NBA Hall of Famer is a big Michigan State football fan. He tweeted about the 2015 team on a weekly basis as it made its way toward the College Football Playoff and was none too pleased when Michigan fans vandalized his statue before the Spartans played the Wolverines last year. -- Bennett

Joel McHale

The comedian and actor actually played for the Husky football team in the early 1990s. He was recruited to Washington as a rower but walked on to play tight end for two years. Actor Jim Caviezel, best known for his performance in "The Passion of the Christ," is also a Husky fan, as his brother played basketball for Washington. Guns N' Roses bassist Duff McKagan, a Seattle native, has been to numerous Husky practices. His nephew, Dexter Charles, recently started on the offensive line for the Huskies. -- Lombardi

Paul Wall

The man who put "grillz" on the map is a huge Cougars fan. In December, rapper Wall and his jeweler, "TV Johnny" Dang, fit Cougars coach Tom Herman for a diamond grill that he sported in the lead-up to Houston's Chick-Fil-A Peach Bowl win over Florida State. Wall, whose given name is Paul Michael Slayton, attended UH for three years, and the school is mentioned on several tracks he has recorded. -- Sam Khan Jr.

Brooklyn Decker

The Tar Heels have a boatload of big names who follow the football team, from star hoops coach Roy Williams to country music star Chase Rice to NASCAR's Dale Earnhardt Jr. But if we have to pick one, it'd be Decker, the actress and model who grew up in nearby Matthews, North Carolina, and has been a rabid Tar Heels fan her entire life. -- Hale

Ty Burrell

Burrell, best known for his starring role in the sitcom "Modern Family," grew up in southern Oregon. Naturally, he has been a Ducks fan his whole life, and he hasn't been afraid to show it, now that he has reached celebrity status. Look no further than a 2015 video in which Burrell posed for a picture in a bathtub with three live ducks to broadcast his fandom in a very literal way. The stunt came while Oregon was struggling last season, so Burrell is certainly not a bandwagon fan. -- Lombardi

Bob Schieffer

The Emmy-winning newscaster and journalist is a TCU alum and Horned Frogs football fan. Schieffer was the host of CBS News' "Face the Nation" from 1991 to 2015, and he continues to take an active role in giving back to the school. -- Chatmon

President George H.W. Bush

Does it get bigger than a former president? The Aggies have a huge fan in former President George H.W. Bush. His presidential library is located on the Texas A&M campus, and he has said that he and his wife, former first lady Barbara Bush, are "Aggies to the core." The couple even attended Johnny Manziel's pro day back in spring of 2014. -- Khan

Jaleel White

White -- best known for his performance as Steve Urkel on "Family Matters" -- is a Bruins fan who was born in Pasadena and attended UCLA. This one might be even better in a football sense, though: Sean Astin, who played Rudy in the movie about Notre Dame football, went to UCLA. "I'm 51 percent Bruin, 49 percent Irish and 100 percent anti-USC," Astin once said. We can also count Snoop Dogg, a longtime USC supporter, in the UCLA camp -- at least temporarily -- because Snoop's son, Cordell Broadus, currently plays for the Bruins, and we've seen Snoop in a baby blue jersey. -- Lombardi

Ashton Kutcher

Kutcher grew up in Cedar Rapids and briefly attended Iowa before dropping out to pursue a modeling opportunity. Things have worked out pretty well for him, but he maintains his Hawkeye fandom. He can be spotted occasionally on the Kinnick Stadium sideline. There is no word on whether he has converted wife Mila Kunis into an Iowa fan. -- Bennett

Luther Campbell

An unofficial ambassador for the program, 2 Live Crew's Uncle Luke is certainly one of Miami's most vocal fans. Campbell can often be found tweeting about his hometown Hurricanes. During the 1980s and '90s, he was sort of a football donor. -- Shanker

Tom Jackson

Jackson remains loyal to his alma mater. The ESPN NFL analyst led the Cardinals in tackles in each of his three seasons playing for the school. His number 50 is retired by the program. A mention here must be saved for the late Muhammad Ali, the Louisville native whose fandom and presence around the program remained strong up until the very end. -- Fortuna
