"The Monster" by Eminem featuring Rihanna jumps to #1 on the Hot 100, displacing Miley Cyrus' "Wrecking Ball." "The Monster" is Eminem's fifth #1; Rihanna's 13th. It's their second #1 together: "Love The Way You Lie" logged seven weeks at #1 in 2010.

Since 1955, only four other artists have had 13 or more #1 hits. The Beatles lead with 20, followed by Mariah Carey with 18, Elvis Presley with 17 and Michael Jackson with 13. (Diana Ross joins this list if you combine her six solo hits with 12 she had fronting the Supremes.)

This latest #1 enables Rihanna to push ahead of Madonna, whose tally of #1s has been stuck at 12 since "Music" in September 2000.

In pulling ahead of Madonna, Rihanna also becomes the one-named solo artist with the most #1 hits in chart history. Here are all one-named artists who have had four or more #1s: Rihanna (13), Madonna (12), Usher (nine), Prince (five), Ludacris (five), Beyonce (five), Eminem (five), Nelly (four), Cher (four) and P!nk (four).

For all her success, Rihanna is still just 25 (she will turn 26 on Feb. 20). A few individuals were even younger when they landed their 13th #1 hits. Paul McCartney and George Harrison were both 24 in March 1967 when the Beatles landed their 13th #1, "Penny Lane." Elvis Presley was 25 years and seven months old in August 1960 when he landed his 13th #1, "It's Now Or Never." (The Fine Print: I'm counting the double-sided blockbuster "Don't Be Cruel"/"Hound Dog" as one #1.)

Eminem is the first rapper to land five #1 hits as a lead or co-lead artist. "The Monster" follows "Lose Yourself," "Crack A Bottle" (a collabo with Dr. Dre & 50 Cent), "Not Afraid" and the aforementioned "Love The Way You Lie." Ludacris and the artist formerly known as Puff Daddy have also had five #1 hits, but both tallies count featured credits. Puff (a.k.a. Diddy) has been a lead (or co-lead artist) on four of his #1s. Ludacris has been a lead artist on only two of his.

"The Monster" holds at #1 on Hot R&B/Hip-Hop Songs for the sixth week.

"The Monster" reached #1 on the U.K.'s Official Singles Chart on Nov. 9. It's Eminem's second single to reach #1 in both the U.S. and the U.K.; Rihanna's seventh. Eminem's previous transatlantic #1 was the Oscar-winning "Lose Yourself." Rihanna's previous songs to reach #1 in both countries are "Umbrella" (featuring Jay Z), "Take A Bow," "Only Girl (In The World)," "What's My Name?" (featuring Drake), "We Found Love" (featuring Calvin Harris) and "Diamonds."

Only the Beatles had more "transatlantic #1 hits" than Rihanna. They had 13 (and McCartney, Lennon and Harrison each had one more on their own). Elvis Presley is in third place with six. Madonna is next in line with five.

"Timber" by Pitbull featuring Ke$ha jumps from #4 to #2. This marks the first time that collabos that pair a male solo artist and a female solo artist have held the top two spots simultaneously since the summer of 2010, when "California Gurls" by Katy Perry featuring Snoop Dogg and "Love The Way You Lie" held the top two spots for six straight weeks (switching the lead at the midway point). "Timber" is #1 on Hot Digital Songs for the second straight week. The song tops the 1 million mark in digital sales this week.

Avicii's "Wake Me Up!" holds at #6 for the second week. The smash reaches the 3 million mark in digital sales this week. It's #1 on Dance/Electronic Songs for the 14th week.

Katy Perry's "Roar" drops out the top 10 this week, but it tops the 4 million mark in digital sales in its 17th week. That's faster than any other song in digital history. Perry also held the old record: Her 2011 smash "E.T." (featuring Kanye West) topped the 4 million mark in its 18th appearance on Hot Digital Songs.
