Brody Jenner, AnnaLynne McCord, Sophia Bush, Joel Madden, Solange Knowles and Cody Linley are all going back to school -- for clothing company Op's "OPen Campus" campaign.
The latest campaign featuring the stars showcases them getting ready for the back-to-school season on a custom Op bus. The ads will debut this fall in magazines and online.
"The Op clothes are so cool," Jenner said in a statement. "This is what I wear on an everyday basis in Malibu. I also enjoyed the Op bus. It has lots of old-school Op decorations. I wish I had this bus in high school!"
The vintage bus, which was retro-fitted with a performance stage on the roof, recycled cork floors, solar panels, Op-decorated skateboards and surfboards and a brand-new gaming system, will also be fetured on TLC's West Coast Customs later this summer.
Between takes, Jenner and Disney star Linley palled around on the skateboards while the women -- including One Tree Hill star Bush and 90210's McCord chatted on the bus.
"Op is all about having fun," said McCord, who also appeared with the other stars in Op's summer beach campaign. "The cast is now great friends and we had a lot of fun shooting this campaign and showing off what's going to be in style for back to school."
