Kelly Monaco, Kelly Osbourne and Shanna Moakler at The Bank.

On Sunday, “Fashion Police” co-host Kelly Osbourne joined actress and Season One “Dancing With the Stars” winner Kelly Monaco for her birthday celebration along with best gal pal, former beauty queen and Playboy playmate Shanna Moakler at The Bank Nightclub at Bellagio following the pairs’ lavish dinner with friends at Fix Restaurant & Bar right next door. The trio, who all attended the 2011 Daytime Emmy Awards earlier, excited the crowd at The Bank, dancing on top of the nightclub’s banquette’s along to the beat’s provided by DJ Karma, while laughing and posing for photos with one another. To end the fun-filled evening, the birthday girl was completely surprised when she was presented with a two-tier custom-made cake topped with her 2005 Maxim Magazine issue cover, brought out with sparklers!

Also on Sunday night, funny man Andy Cohen, hosted the official “Watch What Happens Live!” after-party at The Beatles Revolution Lounge at The Mirage during their popular LGBT weekly event, Closet Sundays, coming straight from judging this year’s Miss USA Pageant and filming an episode of the Bravo show.

Cohen, along with Brovo’s “Million Dollar Listings” stars Madison Hildebrand and Josh Flagg entertained party-goers all night long, giving shout-outs on the mic and dancing to the sounds of the deejay who kept energy levels high mixing up sounds behind the turntable.

Other guests on-hand for the fete, including Caroline Manzo from “Real Housewives of New Jersey” and Emmy Award-winning writer Bruce Vilanch, who was in town judging Celine Dion’s performance at her sold-out show in Las Vegas gig, spent the evening mingling with friends while sipping on specialty cocktails and playing with Revolution’s interactive table tops.
