Lindsay Lohan Gets Grilled About Rehab on 'Late Show': 'It's a Blessing, Not a Curse' (Video)

The star of the upcoming "The Canyons" tells David Letterman she sees the court-ordered treatment as "an opportunity … to focus on what I love."

Repeat offender Lindsay Lohan stopped by CBS' Late Show With David Letterman on Tuesday, where the talk-show host brought up the actress' upcoming court-ordered rehab stint.

"Aren't you supposed to be in rehab now?" David Letterman, 65, asks the 26-year-old starlet.

"Do you not watch anything that goes on?" the star of the upcoming Scary Movie 5 and The Canyons replies, looking more than a little miffed -- though hardly surprised -- at the direction the conversation has taken.

Letterman then presses for details.

"What are they rehabbing, first of all? What is on their list?" he asks, with Lohan sniping back, "We didn't discuss any of this in the pre-interview."

"This is an opportunity for me to, you know, focus on what I love in life. And I don' t think it's a bad thing. I think it's a blessing, not a curse," Lohan reasons, to a smattering of audience applause.

Lohan was given the 90-day sentence in a locked rehab facility after pleading guilty in March of lying about her involvement in a Porsche crash on Pacific Coast Highway, a violation of her parole for drunk driving and shoplifting charges that date back to 2007.

She begins the stint May 2.
