Ke$ha performs at Chateau.

“Tik-Tok” the party definitely didn’t stop on Saturday night at Chateau Nightclub & Gardens when pop sensation Ke$ha put on a performance at her official “Get Sleazy” tour after party at Paris Las Vegas.

Ke$ha arrived at Chateau a little after 1 a.m. to walk the red carpet wearing black Raybans, black fishnets, vintage black shorts and a custom made black and silver rhinestone corset designed by the pop star herself. The platinum-selling recording artist was overheard telling reporters how Chateau was in for an incredible performance and how much she loved Las Vegas.

Once inside the nightclub, Ke$ha’s “bottle of Jack” mentality was right on par when her entourage of 45 took over Chateau’s VIP section, drinking Jack Daniels, Grey Goose and Patron shots while dancing nonstop.

Ke$ha took the stage shortly after arriving and performed her hits such as “Your Love is My Drug,” “We R Who We R” and “Tik Tok.” The crowd really went crazy when she told Chateau party-goers to put their drinks up in the air and proceeded to shower the crowd with mass amounts of glitter.

Also seen at Chateau on Saturday night was Ke$ha’s “Blow” video co-star James Van Der Beek. The “Dawson’s Creek” star walked the red carpet with the pop star and was overheard saying how much fun it was to do a music video with the blonde bombshell. Van Der Beek was in Las Vegas with his wife Kimberly Brook, his parents and friends for a Mother’s Day celebration. Van Der Beek and his party danced the night away at their VIP table while drinking Grey Goose cocktails and Patron shots.

Levi Johnston kept the party going for the second night in a row at the exclusive nightclub, while Floyd Mayweather Sr., the father and former trainer of five-division boxing champion Floyd Mayweather Jr., and former NFL defensive end and Super Bowl champion Michael Strahan were also seen the stunning nightclub.
