Jen exposes all

She may be America's sweetheart but on the latest cover of America's GQ magazine, beautiful Jen surprises everyone.

Showing off her amazing body, the star poses with nothing more than a red, red, white and blue tie - and looks fantastic!

GQ try to get to the bottom of the pregnancy rumours for Jen and her on again off again beau, John Mayer

"I am not having his baby -- and I have not popped the question," Jen jokes
