Britney Spears, Kim Kardashian, Leonardo DiCaprio, Among Guests At Billionaire’s Birthday Party "Guests and celebrities understood photos were totally off-limits." While you were sleeping, one Chinese billionaire was having the party of the year. Saturday night (Nov 3) in a massive rented tent at the foot of the Wynn Hotel in Las Vegas, a star-studded bash rivaling even the best Academy Awards parties, was secretly being held behind throngs of presidential-style security, four checkpoints deep. The ultra private event was a birthday party for a Chinese billionaire simply referred to as “Jay Lo.” A source inside the party told CBS Local “security was matched only by what you would imagine from the Secret Service. Guests and celebrities understood photos were totally off-limits.” The party had a unique dress code as well. “Everyone, including celebrities and talent, were required required to wear either a tuxedos or a red dress.” For inside the 300 person VIP-only shindig was a cavalcade of celebrities including Robert De Niro, Tobey Maguire, Jamie Foxx, Benicio Del Toro, Zack Galifianakis, Britney Spears, Pharrel Williams, Busta Rhymes, Leonardo DiCaprio, Olympic medalist Michael Phelps, Korean pop-sensation Psy, Ludacris, Kanye West, Kim Kardashian and more. Not your normal drink service, complimentary cocktails included entire bottles of Crystal, slid across a 24-foot bar carved from solid ice. Straight out of The Wizard Of Oz, more than 20 umpa loompas frolicked throughout the party while scantily clad Circue Du Solei-style aerial acrobats performed overhead. “At one point, DiCarprio was rapping on stage with Q-Tip and Busta Rhymes.” When it came time to sing happy birthday, one Miss Britney Spears stepped up to the do the honors, after which, a friend reportedly presented the birthday boy with a rather unique 4-wheeled gift; a Bugatti Veyron, a 1000+ horsepower, $2.5M supercar. http://kroq.cbslocal.com/2012/11/04/britney-spears-robert-de-niro-leonardo-dicaprio-among-guests-at-billionaires-birthday-party/
