R&B singer Usher turned 35 on Monday and celebrated with those close to him at Bootsy Bellows in West Hollywood.

Jermaine Dupri, Justin Bieber, Scooter Braun, Sean "Diddy" Combs, Cassie, Blake Shelton, Miguel and Ashley Benson were just a few big names that attended the event.

The singer shared numerous Instagram pictures from the bash and from the looks of it the night included a lot of laughs, dance breaks, a boxing ring-themed cake with a baby photo of Usher in the middle and men dressed up as sumo wrestlers.
