Kaskade DJ'd For 12 HOURS At Marquee's Celeb-Filled NYE Party!

Hopefully he got paid overtime for that! Ha!

Check out the photos (above, and below) of Kaskade performing a 12 hour set on New Year's Eve at The Cosmopolitan of Las Vegas' Marquee Nightclub!

Celebs in attendance at the event included Real Housewives of Beverly Hills' Kyle Richards and hubby Mauricio, 50 Cent, Floyd Mayweather, Lil Kim, Wilmer Valderrama, Topher Grace, Lauren Conrad, and Mark Ballas!

We're not 100% sure how true this is, but we're hearing that Kaskade's performance MAY have been a US record for longest DJ set!

Maybe next year he can go for 24 HOURS! LOLz!
