Jennifer Lawrence [1]'s Monday night appearance [2] on The Late Show with Stephen Colbert was full of big confessions [3], but her comments on her insane work ethic really take the cake. "I puked yesterday. I'm a puker. I'm a big-time puker," she told Stephen. "I think that I don't stop working because I'm a show pony. I don't have a choice. So, I just keep going, I think, until eventually my body's just like, 'If we don't make her barf or pass out, she won't stop.' I get, like, Lindsay Lohan-grade exhaustion but without any drugs or alcohol."

The Golden Globe-nominated actress [4] has been beyond busy promoting her new movie [5], Joy, and getting candid [6] about his highness Saint West, so her zombie status is totally understandable. Watch the video above to see what else Jen had to say!
