Black Eyed Peas ... Police have charged the tour manager of the Black Eyed Peas with assault after he allegedly punched celebrity blogger Perez Hilton outside a Toronto nightclub early Monday morning. Hilton, whose real name is Mario Lavandeira, complained about the incident on the microblogging site Twitter. He tweeted at 4 a.m.: "I am bleeding. Please, I need to file a police report. No joke."

Etta James vs. B... Etta James lashed out against Beyonce when the "Single Ladies" singer performed the James classic "At Last" at President Obama's inaugural balls. In addition to poking fun at the president's big ears (who doesn't?), James threatened to kick Beyonce's butt. James later said she was joking about the entire thing. (Photo by Alberto E.

Christina Aguile... The former Mouseketeers used to be BFFs but when each began a pop music career, the 90s were filled with catfights between the two. You either had to love one or the other – being a fan of both was not an option. Both singers are now mommies; hopefully they'll teach their kids not to indulge in petty rivalries such as their own.

Tupac Shakur vs.... Perhaps the most famous rap feud, this clash ended in tragedy. Tupac Shakur and Notorious B.I.G. started out as friendly competitors from the West coast and East coast respectively but things took a turn for the worse as Tupac began to aim slants at Notorious B.I.G. In 1996, Tupac was shot and killed. Six months later, Notorious B.I.G. was murdered. Their murders have never been solved, although there are numerous speculations. (Photo: MTV); (Rolling Stone)
Michael Jackson ... It may be hard to believe but once upon a time, Michael Jackson and Paul McCartney were once good friends - they even sang songs together. But when Jackson outbid McCartney and Yoko Ono for the publishing rights for many of the Beatles' songs, McCartney broke ties with the king of pop.

50 Cent vs. Kany... It's another battle of the rappers with 50 Cent against Kanye West. 50 Cent said back in 2007 that if West's album sold more copies than his (both albums were being released the same day), that he was going to retire. Well, records show West did outsell 50 Cent yet both are still rapping. (Photo by Kevin Winter/Getty Images for Spike TV); (Photo by Tasos Katopodis/Getty Images)

Vince Neil vs. A... In 1989, Vince Neil punched Izzy Stradlin (Guns N' Roses' guitarist) after a prior incident involving Stradlin allegedly assaulting Neil's wife.

Oasis vs. Blur Oasis' guitarist Noel Gallagher (L) stated he hoped Blur member Damon Albarn would "catch AIDS and die". The two bands always had a rivalry but this remark blew it up to new heights.

Lily Allen vs. K... "I Kissed a Girl" singer Katy Perry dissed Lily Allen when she described herself as a "fatter version of Amy Winehouse and the skinnier version of Lily Allen." Did she think Allen would not be offended? Allen struck back with accusations that Perry doesn't even write her own songs. So far, there haven't been any other big blow ups between the two but we'll wait and see. (Photo by Eamonn McCormack/Getty Images); (Photo by Dave Hogan/Getty Images)
Chuck Berry vs. ... During a live concert, Jerry Lee Lewis allegedly lit the piano on fire in retaliation for Chuck Berry being able to close the show. As he walked off the stage, reports indicate he told Berry, "You're on, Chuck" in an attempt to intimidate the other singer. (Photo by Keystone/Getty Images); (Photo by Getty Images)
Megadeth vs. Met... When Dave Mustaine was kicked out of Metallica for excessive drinking and drug use, he refused to take it lying down - instead, he started his own metal band, Megadeth. The two bands battled it out over the years. Nowadays, it appears the two bands have finally buried the hatchet - just don't expect them to be best friends.

Radiohead vs. Mi... The tween was infuriated when Radiohead refused to let her in their dressing room during the Grammys. She called the band "Stinkin' Radiohead" in a radio interview and went on to say she would ruin them. A spokesperson for Radiohead replied, "When Miley grows up, she'll learn not to have such a sense of entitlement." The question is, will Miley actually learn?
