Frank Mir walks the red carpet at XS Nightclub

Saturday night, ultimate fighters invaded Las Vegas during UFC 132. After the main event concluded, fighters and fans made their way to XS Nightclub at Encore Las Vegas where the official after party was held.

Though he did not fight in Saturday’s event, welterweight Jake Shields scouted future competition and joined passionate fans at the after party, showing his support for the other athletes. Former UFC heavyweight and interim heavyweight champ Frank Mir walked the carpet with his wife Jennifer, then joined the exclusive VIP table reserved for the UFC fighters.

Chuck Liddell, former UFC light heavyweight champion, joined the group to celebrate an evening of fights. Liddell’s extensive background in mixed martial arts lends a hand to his impressive knockout record and induction into the UFC Hall of Fame in 2009. Continuing his duties into the evening, official voice of MMA Bruce Buffer joined the UFC fighters to ensure that the crowd was ready to party throughout the night to an impressive set by DJ Calvin Harris.

Stars joined the UFC fighters at XS including Michael Raymond-James, who plays antagonist Rene Lenier in HBO’s hit vampire series “True Blood.” Joining the actor was Jason Momao, best known for starring in the series “Stargate: Atlantis.”

XS Nightclub’s sister property Tryst Nightclub at Wynn Las Vegas played host to co-main event winner Chris Leben’s celebratory party after his win. Leben knocked out Wanderlei Silva just 27 seconds into the first round. The underdog celebrated into the early hours of the morning with help from SKAM Artist Ross One’s unbelievable lineup of remixes.
