Hayden Christensen Rachel Bilson Harle Yacht cannes

They're on a boat!

Rachel Bilson and Hayden Christensen attended a launch party at Harle Yacht in Cannes for Hayden's new production company Glacier Films. The usually camera-shy couple has been dating on and off since 2007.

The Hart of Dixie star stepped out in style to support her beau, who announced the new production company's 11-picture slate scheduled to shoot over the next three years. Production will begin with American Heist, which Hayden will star in.

Rachel, who donned an adorable Dolce & Gabbana dress with black stockings, will star in the comedy The To Do List with Aubrey Plaza, Christopher Mintz-Plasse, Alia Shawkat, and Andy Samberg. The film hits theaters on August 16.

Despite her busy work schedule, the actress told Cosmopolitan that she's anxious to start a family.

"I definitely have family on the brain," she said. "Having kids is something I want to see in my future -- I hope."

She also said she strives to be the best girlfriend possible.

"I'm a really good girlfriend -- I always put all that first in my life," she told the mag. "I'm definitely the person who would make him his favorite dinner to come home to. ... I love to cook, so we make dinner at home a lot and watch movies."

That explains why we rarely see them out and about.
