Gwynnie Feels Up Conan’s Glutes

Gwyneth Paltrow, appearing on the Tonight Show Thursday night to promote her Web site, Goop.com, showed Conan O'Brien a few exercises to help his self-described body issue of having "no butt."

The Iron Man 2 starlet assisted the new Tonight Show host in an exercise in which he stepped on and off a chair, presumable to build up those glutes. We'll see if Conan heeded the A-lister's advice as we check out his rear end while we compare him to Jay and Johnny over the next few months.

In related news, early online reactions to the appearance Friday focused on her legs, which were noticeably oily and slick in the first set, while tamed down and dry in the next one.

Iron Man 2 hits theatres next summer.
