In case you missed it, Lindsay Lohan was on Late Night with David Letterman last night to promote her upcoming guest appearance on Charlie Sheen's FX series, Anger Management, as well as her cameo alongside him in Scary Movie 5. What started off as a good interview quickly turned a bit sour when Letterman brought up Lohan's impending three-month stint in rehab - and Lohan's face drops before she comments, "We didn't discuss this in the pre-interview."

Considering Lohan was under the impression that she was just there to promote her new projects, do you think Letterman blindsided her with the questions? Or, given how high-profile they are, were they fair game? Either way, we'e gotta say, she handled it pretty well despite the fact that it looked like she was seething inside.
