Saturday night at TAO Las Vegas

New CW television show "Gossip Girl" star Penn Badgley celebrated his 21st Birthday at Tao Asian Bistro and Nightclubon on Saturday. Penn arrived for dinner at 10pm with 12 friends including "Gossip Girl" co-star Chace Crawford (who has been romantically linked to Carrie Underwood), former "Everwood" actore Gregory Smith, former N'SYNC member JC Chasez and "Desperate Housewives" co-star Shawn Pyfrom. The crew dined on some of TAO's signature dishes including Kobe Beef, Chilean Seabass and Pad Thai. Afterwards the crew hit the club where the guys celebrated with shots of Patron and cigars. Penn was surprised when the TAO cocktail staff appeared with sparklers and a birthday cake to mark the occasion, as Chace embraced his friend and costar. The crew stayed into the AM dancing on TAO's catwalk for a bit and celebrating.
