This weekend Las Vegas was full of birthday celebrations! Nick Cannon (along with Mariah Carey) and Mario Lopez celebrated their birthdays at The Bank Nightclub at Bellagio.

On Saturday October 10th Nick celebrated his 29th birthday with wife Mariah, who presented the birthday boy with a cake in the shape of DJ turntables and a message that read, "Happy bday dj sexy fingers Love M.C.C."

Cannon, dressed in a tuxedo, partied in The Bank's DJ booth for over two hours spinning old school hits by New Edition and Michael Jackson while Carey danced by his side.

On Friday October 9th Mario Lopez celebrated his 36th birthday in sin city at The Bank as well. Aubrey O'Day was on-hand to present the former star with his special birthday cake featuring photos of him with Saved By The Bell castmates "Kelly Kapowski" and "Jesse Spano".
