Yesterday was Justin Bieber’s manager, Scooter Braun’s 30th birthday. To celebrate the big 3-0, Braun threw a birthday bash in Hollywood last night and it was a night to remember!! Usher and Bieber gave a duet performance to “Yeah!”, Maroon 5’s lead singer Adam Levine performed “This Love”, and yes, MC Hammer performed as a surprise guest!! Hit the jump to see his performance!! & Happy Birthday Scooter!!
