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.
Bing: Carly Rae Jepsen
In honor of Jepsen reaching the No. 1 spot, we bring you 10 of the best YouTube versions of her hit songs, from Justin Bieber and Selena Gomez's video -- the one that launched "Call Me Maybe" mania -- to versions by Katy Perry, Donald Trump, the Harvard baseball team and even President Barack Obama.
Justin Bieber, Selena Gomez and 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 1 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. Watch it here.
Katy Perry and 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. Watch it here.
Jimmy Fallon, the Roots and Carly Rae
Jimmy Fallon and the Roots can do no wrong, and when Carly Rae herself is thrown into the mix -- with a rainbow-bright xylophone -- the "Late Night" crew gets even better. Plus, Carly plays the triangle, while Jimmy tackles the tambourine and lends some impressive background vocals. And the icing on the catchy pop tune cake: Questlove brought out a kazoo at the end. What's not to love? Watch it here.
The Harvard Baseball Team
Harvard guys can have fun too, as evidenced by the baseball team's choreographed, back-of-the-van lip sync. How's that for a curveball? They could spice up their dance moves a bit -- especially the napping player out in left field -- but all in all we'd say this one was a home run. The entertaining video spawned dozens of replies from university sports teams across the country. Road trip, anyone? Watch it here.
If you want a little indie in your "Call Me Maybe," look no further than Fun. These guys slowed their cover down a teeny bit, focusing on the acoustic guitar and orchestral sounds from the keyboards. Lead singer Nate Ruess' vocals seem to catch a desperation in the lyrics not found in the poppy, catchy original. It's hard to beat Jepsen's version, but these guys sure come close. Watch it here.

President Barack Obama
You know the Internet is doing its job right when a YouTube user (appropriately named Barackdubs) spends countless hours cutting together bits of the president's speeches until we have this masterpiece: Barack Obama singing "Call Me Maybe." Well ... sort of. Obama's team should really consider using this as a campaign tool, since he's calling on the American youth to vote for him later this year. Watch it here.
Miss USA girls, Andy Cohen and Donald Trump
While Donald Trump just sat against a blank wall, eerily staring into the camera, the women of the Miss USA pageant showed off their talents and beauty in their backstage "Call Me Maybe" cover. And, as one would expect, these ladies really know how to work a camera. Bravo's Andy Cohen and E! News anchor Giuliana Rancic both joined in the video, dancing and joking to the pop hit. For a little extra fun, look for the Miss USA tribute-within-a-tribute to the Harvard baseball team. Watch it here.
The Staples Center staff
Everybody dance now! No, seriously, it's like they literally got everyone who works in the Staples Center to dance for this clip. We're talking camera guys, concession workers, ushers, cheerleaders, even TNT reporter Craig Sager, all getting down to the "Call Me" chorus. Maybe the Lakers would have made it to the NBA Finals had they had a cameo ... but now we'll never know. Watch it here.
Miami Dolphins Cheerleaders
Somehow, it's only logical "Call Me Maybe" covers would eventually lead to cheerleaders in bikinis. Miami Dolphin cheerleaders, in this case. These scantily clad women prance around pools, beaches and even take a dive in a ball pit while flirting to the camera on their own version of Jepsen's No. 1 hit. With over 4.5 million views, it's doubtful they have problems getting boys to call them ... maybe. Watch it here.
Tay Zonday, the "Chocolate Rain" guy
Singing in front of a microphone and camera, Tay Zonday (better known as the "Chocolate Rain" guy) puts his baritone spin on the Carly Rae Jepsen hit. Falling somewhere in between a toad and an opera star, Zonday's version sounds more than a little creepy compared to Jepsen's No. 1. We probably won't be calling him anytime soon. Watch it here.
And Carly Rae Jepsen's original ...
Like we said, nothing beats the original, and when all the covers are said and done, it's Carly Rae's catchy tune that sent the song to the top of the Hot 100 chart. Her fun video and its twist ending are the perfect complement to the song, which has sold 3.3 million downloads to date, according to Nielsen SoundScan. Watch it here.
