Jennifer Lawrence Says "That's Not My Butt"

Jennifer Lawrence sat down on the Letterman Show last night to reveal the truth about that saggy bottom bikini pic that's been circulating the internet.

The Golden Globe winner tells Letterman that "it's a 90-year-old butt that's been photoshopped onto my body and is posing as my butt." And to backup her statement, Lawrence shows a not so flattering photo of herself where she looks bloated and without makeup. 

Could she be any cooler?
