Oh you knew Jennifer Aniston wasn't going to show up at the premiere of her latest movie, Marley & Me, looking any less than stunning. Her racy, lacy Valentino mini dress showed off her tanned, toned legs and arms while her sun-kissed skin and long, luminous hair added a youthful glow. Also, all the sex with John Mayer probably helps (yeah we said it).

We might agree with Hugh Hefner, who was just quoted saying, "She gets hotter with age." Or something like that. You know old people and their crazy talk.
