Alex Meraz and Trevor Donovan helps Gossip Girl‘s Jessica Szohr up on a surfboard as they shoot for the 2010 “Rock Your Shine” OP campaign for Walmart.

Joined by Glee stars Cory Monteith, Dianna Argon and singer Cassie, the six took part in a summer block party, hanging out in a hammock, barbequing and getting ready to go surfing.

Jessica shared about the clothes she was modeling off, “The latest trend for spring is shine and Op has it first. The clothes are so great; especially the amazing bikinis and shorts.”
