XS - Cheryl Burke, Rob
Kardashian

Saturday night, the stars
collided at XS Nightclub in Las Vegas
where will.i.am was headlining in the DJ 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, in a simple fitted black shirt,
while Cheryl stood out in a sequined black cocktail dress.

XS - David Guetta, will i am,
Usher

Just before 2 am, a wave of eruptions worked their way through the
club as R&B superstar Usher and electronic phenomenon David Guetta entered
to their table on stage. Usher took a moment to interrupt will.i.am’s DJ set
and greet his fellow artist and friend. Usher was in high spirits, bouncing all
over the stage 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 DJ
booth, with Usher taking the microphone and serenading a sea of screaming fans
below.

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

XS – Jesse Waites, Ryan
Seacrest

Arriving just after 3 am, American Idol host and radio icon Ryan Seacrest and
girlfriend Julianne Hough took over Usher’s seating area, accompanied by two
bodyguards and several friends. Julianne, starring in the remake of Footloose
out on October 14, showed off her skills, dancing at the front of the stage
while hanging onto the DJ 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.

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