Gwyneth Paltrow wears lingerie to seduce Mark Ruffalo in 'Thanks for Sharing' trailer

Gwyneth Paltrow falls in love with a recovering sex addict played by Mark Ruffalo in the new film, "Thanks for Sharing," an upcoming comedy also staring Tim Robbins, Joely Richardson, Josh Gad and Pink.

The trailer gives us a glimpse of one particular scene, in which the 40-year-old actress (who has made a new career out of health food cookbooks and exercise tips) strips down to black lingerie in an attempt to seduce Ruffalo's character.

"There's a line in the movie where somebody says something like, 'Isn't sex addiction just an excuse men use when they get caught cheating?' But actually, it is a real pathology," Paltrow told the Globe and Mail (via US Weekly) when the film debuted at 2012's Toronto Film Fest. "It was interesting to learn about it, see what the behavior is and what causes it, and how people are sober. It was very interesting. I learned a lot."

"Thanks for Sharing" hits theaters Sept. 20.
