via usmagazine.com Rachel Bilson rarely talks about her relationship with Hayden Christensen, her Jumper costar and on-and-off love of six years. In the May issue of Cosmopolitan, however, the Hart of Dixie actress can't help but gush about her life with the Shattered Glass actor. "I'm a really good girlfriend -- I always put all that first in my life. I'm definitely the person who would make him his favorite dinner to come home to," Bilson tells the magazine. "I love to cook, so we make dinner at home a lot and watch movies."
