Chace Crawford really knows how to celebrate a birthday.

The Gossip Girl heartthrob turned 24 on Saturday, and the actor marked the occasion by flying in 15 friends from his hometown of Dallas to New York for the weekend, People magazine reports.

Once they arrived in the New York, Crawford’s Texas homies joined the star and some of his show-biz pals, including Gossip Girl co-star Sebastian Stan and actor Toby Hemingway for a flight to Water Mill, New York, where they partied at a private residence for the weekend. The merry crew indulged in barbecue, drinks, swimming, kayaking and a speedboat ride.

“It was the best birthday Chace ever had because he was amongst his closest friends,” says a source. “His hometown friends got along great with all his New York city pals.”

Sounds like a blast, but where was Chace’s ex-roommate, Ed Westwick? Boy, when Crawford decides he’s done with someone, he really means it.
