Lindsay Lohan popped by The Late Show to promote her upcoming film Scary Movie 5 and FX’s Anger Management. It was her first appearance on the CBS talk show since 2007. Naturally, David Letterman had a lot of questions to ask her, most notably about her upcoming rehab stint.

Whether she was serious about not being asked these questions in the pre-interview, I have to give credit to the 26-year-old. This is the most put together I’ve seen her in a long time and her playful interaction with Letterman was actually entertaining to watch. Don’t take my word for it, watch the two go back and forth about her upcoming rehab stint beginning May 2.
