The Upper East Sider—er, gossip Girl star Chace Crawford unveils his impressive physique on a Memorial Day vacation in Mexico with sister Candice and her quarterback husband Tony Romo.

Crawford, who played clean-cut Nate Archibald on the hit TV show, wore bright red swim trunks and a backwards baseball hat for the day, giving us a clear view of his abs.

It's been more than two years since they said goodbye to the show, and they were all smiles while posing for a picture together.

I miss Gossip Girl :(
