Haute Event: Paris Hilton Dresses as a Ghost for Deadmau5 at the Chelsea

Paris Hilton danced on stage during Deadmau5's performance at the Chelsea.

Marquee Nightclub and Dayclub at the Cosmopolitan of Las Vegas kicked off the club’s Labor Day weekend music marathon on Friday with DJs Chris Garcia, the EC Twins and Roger Sanchez, who played to a packed crowd in the afternoon. Celebrity chef Curtis Stone stopped by to check out the scene.

At Tao Beach at the Venetian, DJ Vice started the party for SKAM Artist Fridays.

The holiday weekend celebration continued at Marquee Nightclub with DJs Blake Jarell and Armin Van Buuren. Paris and Nicky Hilton arrived at the hot spot with friends around 3 a.m. after joining thousands of party-goers at The Chelsea at the Cosmopolitan of Las Vegas for the massive Deadmau5 stage production. Served by sexy servers in the Marquee VIP area at the concert, the ladies hung out at their stage view table as Deadmau5 entertained the crowd with his electrifying stage production. At the concert, Paris even got in on the show by performing on stage dressed up as a ghost during Deadmau5’s huge hit, “Ghosts n Stuff.” She revealed herself and danced on stage in a sexy white mini-dress.

Also spotted at Marquee on Friday night was Matthew Settle, who plays dad Rufus Humphrey on “Gossip Girl.”

Cedric Gervais spun for a packed crowd at Tao Nightclub while the EC Twins entertained club goers at Lavo at the Palazzo.
