Blake Lively and Chace Crawford in Gossip Girl Wrap Party Pics—Check 'Em Out!

Actors join fellow costars to say goodbye to the show that made them household names

All good things must come to an end. But that doesn't mean you can't have a little fun while it's happening.

That's just what much of the cast and crew of Gossip Girl did on Friday when they gathered for a wrap party to mark the show's final season.

"All together," Chace Crawford captioned a photo he posted on Facebook that included costars Ed Westwick, Michelle Trachtenberg, Leighton Meester and Penn Badgley revealing quite the new 'do.

Crawford also posted another pic that showed him covered in frosting while clearly enjoying a little farewell dessert.

"Eating the cake," he wrote.

Meanwhile, a shot of Blake Lively also enjoying the festivities with Crawford and Westwick also made its way to the Internet.

Gossip Girl began airing on the CW in September 2007. The series finale is scheduled for Dec. 10.
