Which "Gossip Girl" stars were on hand to relaunch Ray Ban's Club Master sunglasses? Most of them, as a matter of fact -- Blake Lively, Penn Badgley, Chace Crawford, and Ed Westwick stepped out earlier this week to support some of their favorite shades (even if they are too young to remember them the first time they were popular).

Judging by the popularity of the Wayfarer's relaunch, the Club Master has a good shot at being a must-have accessory this spring and summer. It's a classic and iconic shape, easily recognizable as the style that was worn by Malcolm X and Katherine Hepburn.

Don't let the "Gossip Girl" crew have all the fun -- you can get a pair of Club Masters for yourself at a Sunglass Hut near you for about $130.
