How did Gossip Girl‘s Vanessa Abrams find herself in a cuddle puddle with Glee clubbers Finn Hudson and Quinn Fabray? The trio–Jessica Szohr, Cory Monteith and Dianna Agron–are starring in this spring’s upcoming ad campaign for juniors clothing brand Op, along with R&B singer Cassie, 90210‘s Trevor Donovan, and Alex Meraz of The Twilight Saga: New Moon and Eclipse. The “Rock Your Shine” campaign, shot by photographer Larry Bartholomew, is set at an imagined summer block party, and features the young stars lounging in a hammock, barbecuing, and getting ready to head out surfing, all while wearing sexy and sweet beach-ready pieces. “The clothes are so great; especially the amazing bikinis and shorts,” says Szohr of her favorite pieces from the line, which is available exclusively at Walmart. And if it looks like they’re having fun, it’s because they are: Says Dari Marder, Chief Marketing Officer of Iconix Brand Group, which produced the collection, “The cast had a blast, since some of them were already great friends, and even co-stars. The rest made lifelong friends after a long, fun day on set.” Watch the video below for a behind-the-scenes peek at their fun-filled time shooting, and look out for the ads to break in May issue of fashion magazines and online. –Marissa Patlingrao Cooley[brightcoveplayer 74731925001]
