Gossip Guy Turns 21 Minus His Costar

Ed Westwick celebrates in Sin City; laughs off rumors about his relationship with Chace Crawford

A little gossip doesn't bother Ed Westwick.

"I just laugh it off," he tells People about the rumors that he and his Gossip Girl costar (and roommate) Chace Crawford are more than just friends.

"People who know me and Chace and the cast know that we are all great friends," Ed tells the mag. "And that's the extent of it all. Those things that go around are just amusing to us, really."

But how does Chace feel?

Who knows? He was expected to attend his friend's celebration but canceled at the last minute.

Still, Ed had plenty of company for his 21st birthday weekend even without his costar. Thirty friends and family members joined him for dinner at Tao. After the meal, he headed to a VIP table at the nightclub upstairs, where he had his first legal drink.

His beverage of choice? Champagne.

Chuck Bass would be proud.
