On Tuesday's airiing of the "Late Show," host  David Letterman appeared to catch guest, Lindsay Lohan off guard with a series of questions regarding her rehab teatments.

The truth is, I would be the last to defend Lohan, not a fan and really don't  have much interest in her. However, Letterman came off as a jerk, as he clearly put Lohan in an uncomfortable position. Now I know he's a comedian and just trying to get laughs but some are saying he went to far. I have to admit, I myself felt a lttle awkward watching this on television and could only imagine how some in the audience felt. I do have one theory, maybe Letterman sensed Lohan was a "little off." If you look at her, she looks a bit out off it or maybe just tired.  Well the video is up, so you be the judge.
