Actress Jessica Simpson has refused to rule out a future boob job - because she can't bear the thought of her best features sagging. The busty star insists her current pair are real but she isn't afraid to go under the knife to keep them looking good as she ages. She tells Bazaar magazine, "I've had none (plastic surgery). But maybe after having kids, if my boobs dropped down to my belly button, I would get them lifted... Maintenance. But you know, my boobs are real." And even though her sister Ashlee is believed to have undergone a nose job, the Dukes of Hazzard star is adamant her breasts aren't the only thing she has kept real in Hollywood. She adds, "People have said that I've had things like a jaw replacement or implant or something. I'm photographed every day of my life and have never worn any bandages or anything, so how could that be right?"
