Call Me Maybe

After months of covers, flashmobs and radio play, Carly Rae Jepsen has finally dethroned Gotye to take the top spot on the Billboard Hot 100 chart. Her hit single is as catchy as it is popular, and even celebs have gotten in on the "Call Me Maybe" action, recording covers and viral video interpretations of the song.

Carly Rae Jepsen's 'Call Me Maybe' Hits No. 1 on the Hot 100

In honor of Jepsen reaching the No. 1 spot, we bring you the 10 best YouTube versions of her hit songs, from Justin Bieber and Selena Gomez's video -- the one that launched "Call Me Maybe" mania -- to clips by Katy Perry, Donald Trump, the Harvard baseball team, and even President Barack Obama.

Justin Bieber, Selena Gomez & Ashley Tisdale

Few cover videos ever beat the original, that is until Justin Bieber and Selena Gomez get involved. Carly Rae Jepsen might not have climbed to No. 1 on the Billboard Top 100 if it weren't for The Biebs and Co. endorsing her catchy single. Their video, which sparked the "Call Me" craze, raked in a million views during the first 24 hours. The power couple of pop danced with fake mustaches and banana telephones alongside pals Ashley Tisdale, Big Time Rush, Boys Like Girls and more.

Katy Perry & Friends

Inflatable monkeys, iPhones and mixed drinks are all heavily featured in Katy Perry and friends' version of "Call Me Maybe." No stranger to being goofy, a purple-haired Perry bounces across the screen while lip-syncing, then plays director, shouting out stage directions to her pals. Shot during Coachella weekend, the video was a response to the Biebs' version, with Perry giving him a shout-out at the end.
