Haute Event: Will.i.am, Usher and David Guetta Share the DJ Booth at XS Nightclub

David Guetta, Will.i.am and Usher take over the deejay booth at XS Nightclub.

Last night, the stars collided at XS Nightclub at Encore Las Vegas where Will.i.am was headlining in the deejay booth. Rob Kardashian and his “Dancing with the Stars” partner Cheryl Burke were the first to arrive to the evening festivities, practicing their new moves in an exclusive VIP table raised above the dance floor. Kardashian was showing a slimmer figure from the intense competitive training wearing a simple fitted black shirt, while Burke stood out in a sequined black cocktail dress.

Just before 2 a.m., a wave of eruptions worked through the club as R&B superstar Usher and electronic phenomenon David Guetta entered to take their table on stage. Usher took a moment to interrupt Will.i.am’s deejay set while he greeted his fellow artist and friend. Usher was in high spirits, bouncing all over the stage while breaking out his signature dance moves, taking shots of Patron and mingling with his friends. When Will.i.am dropped Usher and Guetta’s latest hit collaboration, “Without You,” the two both immediately jumped into the deejay booth, with Usher taking the microphone and serenading a sea of screaming fans below.

Usher’s entourage included “Pretty Little Liars” starlet Ashley Benson, who wore a black mini-dress with open lace back. She was seen dancing on stage with two gal pals sipping Grey Goose cocktails before moving out of sight from the crowd below to steal a few secluded moments with Ryan Good, who is rumored to have been hired by Usher to be Justin Bieber’s swagger coach. Good held Benson’s cell phone, poured her drinks and held her hand throughout the evening. The two were spotted whispering sweet nothings to each other and canoodling on stage.

Arriving just after 3 a.m., “American Idol” host and radio icon Ryan Seacrest and girlfriend Julianne Hough joined Usher’s seating area accompanied by two bodyguards and several friends. Hough, who is starring in the remake of “Footloose” due out on Oct. 14, showed off her skills, dancing at the front of the stage while hanging onto the deejay booth into the early hours of the morning. Seacrest admired from afar, watching from their VIP couch while chatting with XS Managing Partner Jesse Waits.

Also spotted on stage, The Black Eyed Peas member Apl.de.ap, UFC champ Tito Ortiz and wife Jenna Jameson, plus DJ Pete Tong.

In a separate group, “Twilight” star Christian Serratos, best known for her role as Angela in the vampire saga, rang in her 21st birthday at the club and was presented with a three-tier themed cake in celebration. Surrounded by close friends, the actress donned a silver party dress and danced all night.
