VIDEO: Lindsay Lohan talks rehab, cries on Letterman

Lindsay Lohan was on Letterman on Tuesday to promote her forthcoming film, Scary Movie 5. The two were joking back and forth, with him reading her jokes he's cracked at her expense. Then, Letterman transitioned with an abrupt, "Aren't you supposed to be in rehab now?"

LiLo tries to convince Letterman to stick to questions about her movie, which is a thing that actually got made. Eventually, she swipes his question sheet and hilariously reads a bunch of them off. Lohan gets into the emotional stuff and explains that she's looking forward to turning her life around.

"I'm a target. I've always been. And I've put myself, in the past, in situations where, you know, I take full responsibility for it. And, it wasn't funny and I was being immature and I was going through a phase and I had a lot of family stuff going on and things in life... You grow up and you mature. I've said that a million times, I know that. But, what else am I supposed to say when it's a process of life and I'm not trying to deny any situation I've been in."

The two go back and forth riffing with Letterman's question sheet for a bit, before discussing Charlie Sheen and his antics. When Letterman goes to introduce Lohan's Scary Movie 5 clip, he asks if she's going to be at the premiere or if she'll already be in rehab. She's clearly agitated. He pushes and asks who's taking her to rehab. Lohan answers, "Jimmy Fallon."

BOOM!

At the end of the interview, Letterman thanks her for having the courage to come on the show after all of the jokes he's cracked over the years. Lohan gets emotional as Letterman says that he loves having her on the show.

The whole 14-minute interview is very entertaining, even if just to see Lohan playing off the rehab stuff and Letterman pushing her to talk about a little more than she'd like to before thanking her and making her cry by "being so sweet."
