Sandra Bullock is happy sitting back and letting her husband Jesse James take care for her needs. "I've had to learn a hard lesson in that I'm not allowed to open car doors anymore," Bullock says in the new issue of Harper's Bazaar. "It was so hard for me to allow someone to take care of me. It's not because I can't take care of myself. But Jesse was like, 'Just let me do this.' " Without kids of her own, Bullock is content playing the good stepmom to James' kids: Jesse Jr., 11, Chandler, 14, and Sunny, 5. (Photo: WENN)
