Young Hollywood joined forces with Westcoast Hip Hop Tuesday night when Snoop Dogg and Travis Barker hosted a supersize bash at LA's Vanguard.
The party was in honor of Snoop Dogg's tenth studio album, Malice in Wonderland, and the tenth anniversary of Travis's clothing line Famous Stars and Straps.
During the show - which lasted more than an hour - Travis played drums while Snoop held the mic. Pharell Williams, The Black Eyed Peas Apl.de.ap, The Game, Warren G and Nate Dogg all came on stage to help Snoop sing a huge list of his hits.
Kelly Osbourne and blonde boyfriend Luke Worrall danced and locked lips to Snoop and Pharell singing Beautiful. "Kelly looks amazing! She and Luke seem incredibly in love, he had his arms circling her waist and his head on her shoulder, they were really sweet," a party insider exclusively told RadarOnline.com.
Entourage's Kevin Connolly hung with cast members of 90210 but for some reason seemed to want to hide! "He was behind a curtain in the VIP booth closest to the stage. Every time a song came on that he liked he would pop out and start dancing on the top of the banquette. Then as soon as it was over he would go behind the curtain again - it was hilarious!" dished an onlooker.
After the show, Snoop and Travis held court in a private upstairs VIP room reserved strictly for close friends and family. "Travis was in a really great mood. He kept toasting with his friends who were all decked out in Stars and Straps gear. Then someone brought up DJ AM and things got a bit sombre. It was clear Travis is still really hurting."
