CHICAGO — Da Bears have a new set of Super Fans — Da Sisters.

They are Bears head coach Marc Trestman’s daughters Chloe and Sarahanne Trestman, of course.

The Trestman girls are not exactly the fat, mustachioed Bears fans parodied on "Saturday Night Live" and those State Farm "Discount Double Check" commercials.

But Chloe and Sarahanne's social media celebrations of their Papa Bear's new team — and their online interactions with each other — are just as hilarious.

Plus, their tweets, Instagram pictures and Vine videos offer Bears fans a rare peek at what the rather stoic Bears coach's home life is really like. Following them on social media is like watching an online reality show.

Chloe, 19, and Sarahanne, 21, have adopted #BearDown as a favorite hashtag catchphrase and offer up video proof that they're learning the words to the Bears' fight song. They love Chicago, too. Especially, this guy.

And while their famous father is quarterback Jay Cutler's boss, Sarahanne, who works at a juice bar in the suburbs, once served tasty drinks to Cutler and his reality TV wife, Kristin Cavallari.

"@KristinCav Hope you and Jay enjoyed your ... juices this morning!" she tweeted.

Chloe, whose sister recently congratulated her (on Twitter) for getting into DePaul University, has already dressed up her fluffy white puppy, Mac Daddy, in a Bears jersey.

They get a pretty good view of the action on the field, shooting video from insider-access angles.

And at a recent home game Chloe thanked a rather entertaining fan in the crowd below her skybox seats for being "awesome."

And she let Bears fans know via Twitter how her family celebrates a touchdown: “My mom just did a forward role [sic] and my sister started wall twerking after that one.” There wasn't a video attached.

But the girls offer other Internet proof — especially a certain outburst at the GPS — that their mom, Cindy Trestman, is a fiery lady who gets down to Jay Z and likes to dance while driving.

"Mom and the navigational system going at it, it's getting pretty heated," Chloe tweeted, along with a hilarious Vine video.

They even let out the secret that their mom even speaks a little Persian.

The Trestman girls didn't respond to Facebook requests for interview, but Bears fans still can learn a lot about the Trestman girls by surfing social media sites.

Here's a taste ... in their own words:

Sometimes, Da Daughters are goofy.

Other times, they're ornery.

Sarahanne likes locally brewed beer and Chicago deep-dish.

She wonders if she looks like Khloe Kardashian.

They respect Da Coach — Mike Ditka, that is.

Chloe might tweet while driving. And Sarahanne scolds her for it.

They wrestle with their mother and battle each other in front of the bathroom mirror.

They've been known to capture weirdos dancing on the street in Lincoln Park.

But more than anything, social media offers up proof that the Trestman girls really love their family, take Bears football seriously, and they're super proud of their dad.
