Demi Lovato doesn't skip over the swear words. (Getty) Those ex-Disney kids love a good cover. Demi Lovato treated her first tour audience in Detroit, Michigan to Maroon 5's hit "Moves Like Jagger" this week! And she CUSSED!

Also, Justin Bieber and Jaden Smith took it upon themselves to remix Frank Ocean, Katy Perry's planning to take some time off (BABIES?!??!?), and Nicki Minaj is allegedly getting ridiculously divaliciousso much so that the American Music Awards producers are in a tizzy.

Demi Lovato kicked off her North American tour in Detroit, Michigan on Wednesday, delighting the audience with all her bubbly hits and a cover of Maroon 5's overplayed ditty "Moves Like Jagger."

Unfortunately, Demi's Jagger moves consisted of waving her arm around a lot (we would have liked to see her do that weird prancy thing Mick mastered all those decades ago). But she stayed on key, and she even kept the lyrics intact, clearly singing, "I don't give a s**t" to the delight of her underage fans.

Justin Bieber and Jaden Smith showed off their new manly vocal registers on a cover of Frank Ocean's "Thinking 'Bout You," which the pair uploaded to YouTube yesterday. It's a total boner jam, which is weird, 'cause both of them are super underage so should they even be making boner jams? Whatever.

Also, Justin's rap is superior to Jaden's.

The New York Post reports that Katy Perry has informed her managers she'll be taking a year off after her California Dreams tour wraps up next week. Her reason? She wants to "work on her family."

We're getting ahead of ourselves here, but Katy Perry's going to be the cutest pregnant celebrity EVER. There's no way she's not going to work a billion cutesy costumes around that bump, even if she is taking time off.

But we'll have to wait on that, since Perry told her NYC audience this week that she's not pregnant, but bloated from "New York City pizza." Uh huh.

Nicki Minaj has apparently upset the producers of the American Music Awards by insisting that British YouTube stars Sophia Grace Brownlee and her cousin Rosie be involved in her performance, which has made the whole ordeal pretty expensive. Also, she plans to use "electric vibrating prop" during her performance, which sounds kid-friendly!
