Jennifer Aniston Strips For 'GQ' Admitting: 'I Hated My Thirties'

Jennifer Aniston is 43. FORTY THREE!

With a body like that it's hard to believe she's not at least 10 years younger, despite the star saying her "thirties blew" and her "forties are great".

The actress whipped off her top for a shoot with US GQ magazine, showing off her toned figure in a black bikini top and denim skirt.

Jen teamed up with her former Friends co-star Paul Rudd (who played Phoebe's husband Mike in the US comedy) for the shoot as the pair prepare to release new film Wanderlust, which also stars Jen's current squeeze Justin Theroux.

There had been rumours circulating her and Justin were expecting a child together, but Jen quickly denied the claims in the interview with the mag.

"Well, I recently quit smoking, and you do put on some extra pounds. It makes a difference, especially if you're not 20," she said.

"I think people maybe want me to have a kid now. I still kind of go with, if it happens, it happens. I'm calm and peaceful with whatever the plan is. It's not something where I'm going, 'I gotta have a kid!'"

The full interview appears in the March issue of the US edition of GQ magazine. For more information, visit
