Jennifer Aniston: My Body & Me!

Jennifer Aniston shows off her legs for days in a Valentino LBD at the premiere of her new film, Marley & Me, held at the Mann Village Theater Westwood, Calif., on Thursday night.

The 39-year-old actress, who carried around a red Ferragamo clutch, has everyone talking about her smokin’ body after her revealing GQ photoshoot. Neckties anyone?

Boyfriend John Meyer and co-star Owen Wilson were on-hand for the festivities. And of course, Marley!
