Summer just started three days ago, but the OP clothing line is turning its eye towards going back to school - with celebrity fashion icons promoting the cause.
Some of Hollywood’s hottest young stars are posing for the brand's “OPen Campus” campaign, including 90210 star AnnaLynne McCord, One Tree Hill's Sophia Bush, Solange Knowles, Joel Madden, The Hills' Brody Jenner and Cody Linley.
The sexy sextet posed on a custom OP bus by West Coast Customs that has everything from a stage on the roof to recycled cork floors and a gaming system.

TOO COOL FOR SCHOOL: Six young Hollywood stars promote OP's fall line.
At the shoot at University High School in L.A., the girls bonded over gossip in the bus while Cody and Brody palled around on skateboards between takes.
Appearing in the ads was not a hard sell for the stars.
"When they asked if I wanted to be involved, I was like, 'definitely!'" said Joel Madden. "Op is a classic California skating and surfing brand. It’s very cool."
"Being from Southern California, I basically grew up wearing Op," Brody Jenner added. "It’s really cool for me to now be part of their new ads."
