One of the things we love most about Drew Barrymore [1] is that she's not afraid to be who she is [2]. During a stop on The Late Show With Stephen Colbert [3] on Monday night, the actress took a walk down memory lane and reminisced about the time she got on top of David Letterman [4]'s desk and flashed her breasts for his birthday in 1995. "In this very theatre I did something in particular with Mr. Letterman," Drew recalled. "I literally was like, 'What?' I sometimes think, like, that doesn't feel like me, it's like a distant memory that just doesn't seem like me." If you need a refresher of the hilarious moment, check out the video below and see what Drew had to say about it.
