Multi-hyphenate, and new Hollywood wonder boy, Jason Reitman offered MTV an update on the horror-comedy Jennifer's Body, directed by Karyn Kusama, and what he had to say is sure make some of our male readers feel a bit tight in the ol' pants region.

Reitman tells the outlet, "We've got [stars] Megan Fox and Amanda Seyfried getting into a fight in their underwear. That'll be fun." Well, that sounds like pure gold to us. Principal photography begins on the Diablo Cody-scripted flick in about three weeks.

Adam Brody and J.K. Simmons most recently joined the cast.
