Drew Barrymore, 34, was on the Late Show last night promoting her new HBO movie Grey Gardens. The actress came out in a tight black dress with poofy sleeves and her hair up in a tight bun. She was super flirty with Dave as usual. Barrymore famously flashed her breasts to Letterman (link leads to video) on his show in 1995, standing on his desk and turning her back to the audience to quickly lift up her top. She was more subdued in this appearance, but kept up the sexiness until it came time to talk about her film, when she got serious and you could tell she really cared about her role. Dave called her performance as Little Edie in Grey Gardens “stunning.” They had a lot of fun banter before talking about the film, with Dave asking Barrymore questions written in from fans.

At one point Barrymore explained her new tongue piercing, sticking it out to show Dave when he asked about it: “You know I’m a good time gal… I directed a film about a roller derby team. I play a charater named Smashley Simpson. I got this [the tongue piercing] cause they all have like, alter egos, they’re all mini super heroes. I got this to play her and I haven’t taken it out is all.”

Letterman jokingly warned her “it will get infected, it’s painful, and you may lose most of your tongue.”

Toward the end of the show, Barrymore thanked a NY city police officer who saved her from men who were chasing her, most likely paparazzi. She said she pulled over and rolled her window down and asked a cop “Sir, will you please help me, these mean awful scary men are chasing me. Will you save me?” and he answered “I love you, Drew Barrymore, I’ll rescue you.” She added “OMG, and you’re cute to boot?”

Dave joked, “that was me and Paul.”

Drew’s new HBO movie, Grey Gardens, airs on HBO on April 18 and also stars Jessica Lange. It’s about the women behind a real 1975 documentary about a mother and daughter who happened to be an aunt and cousin of Jacqueline Kennedy Onassis. The women lived delusional lives of past grandeur while they were trying to make due in a run down old mansion in East Hampton, New York. Here’s the trailer:
