The grand opening of 1Oak at The Mirage in Las Vegas was THE place to ring in 2012! 

Black Eyed Peas front-woman Fergie hosted the star-studded soiree while Kanye West (who dubbed himself Yeezy World Peace for the evening) thrilled party-goers by DJ'ing a three-hour set.

Some of the biggest names in Hollywood joined the musical power-duo to celebrate the beginning of 2012, including Fergie's hubby Josh Duhamel, Kid Cudi, David Katzenberg, Topher Grace, and Joseph Gordon Levitt.  The fellas of Foster The People were also on-hand as was Pretty Little Liars star Drew Van Acker

Despite rumors Kanye has been courting Kim Kardashian, the pair did NOT spend NYE together.  Kim K. was across the way hosting her own 2012 bash at Vegas hot spot Tao while 1Oak attendees noticed Yeezy had a stunning mystery brunette on his arm throughout the evening.

The sweetest part of the 1Oak evening had to have been when Fergie was spotted serenading her hubby with '80s tunes while the most exciting part was no-doubt the 2012 countdown.  Confetti guns blasted thousands upon thousands of white snowflakes into the air and the crowd was loving EVERY minute of it!
