Justin Bieber Parties With Kim Kardashian In Los Angeles!

Adam Levine, Usher & More — all the stars were out for Scooter Braun’s birthday party!

Scooter Braun — the man who discovered Justin Bieber and shared his gifts with the world — turned 30 on June 18, and to celebrate he threw a lavish carnival-themed birthday party with some A-list buddies!HollywoodLife.com was at The Music Box in Hollywood for the shindig and got a glimpse of all of the action!

Justin, 17, was there supporting his manager, spending much of the night hanging with his buddy JadenSmith. But it was easy for him to get distracted by all the extravagance. The carnival theme was wild, with fire throwers and belly dancers. And the entertainment? Let’s just say it was the top of the A-list!

All of the musical talent there performed, and it was a who’s-who of pop! Justin kicked things off by singing “Never Say Never” with a rap by Jaden, who also took over the Ludacris part in “Baby.” Then MC Hammersomewhat randomly ran through some hits, including “Too Legit To Quit.” Usher kept the party going by performing a set filled with hits like “Yeah!”, and although he was shy to get onstage, Adam Levine even belted out Maroon 5′s smash “This Love.”
Meanwhile, a Kris Humphries-free Kim Kardashian was mingling in the crowd, along with celebs such as her frenemy Paris Hilton and singer Mary J. Blige.
It was a great night for one of the nicest guys in showbusiness!
