"Late Show" host David Letterman went straight to the topic on everyone's minds when starlet Lindsay Lohan sat down for an interview Tuesday night: her rehab sentence.
Her troubles weren't exactly what she was there to discuss. The actress is currently promoting her guest role as Charlie Sheen's love interest on the sitcom "Anger Management," as well as a cameo in "Scary Movie 5." In a clip released by CBS, the actress is giggling happily until Letterman asked her, "Aren't you supposed to be in rehab now?"
Her laughter died instantly as she shot back, "Do you not watch anything that goes on? Are you a tabloid now? May 2nd."
In March, she admitted to a Los Angeles judge that she had violated probation, and accepted a plea deal that requires her to stay 90 days in a "locked rehab facility." She is required to prove by May 2 that she has enrolled in treatment.
After Letterman got a few answers from her regarding the length of her stay in rehab and the number of times she's received treatment, Lohan sounded like she wasn't too happy with the line of questioning.
"We didn't discuss this in the pre-interview, just saying to everyone," she told the audience.
But the comedian pressed on for details before she finally cut him off. "To be honest, I'm the happiest when I'm working, and the healthiest. And I think this is an opportunity for me to, you know, focus on what I love in life," she said. "And I don't think it's a bad thing. I think it's a blessing ... and not a curse."
But Letterman still wasn't done with the subject. "Do you have addiction problems?" he asked.
After a stony silence, Lohan finally replied, "Now you sound like Dr. Phil," and wouldn't give him details.
Tuesday's interview is the first one she's done since November 2012.
Watch her entire interview Tuesday when "Late Show With David Letterman" airs at 11:35 p.m. on CBS.
