Lindsay Lohan appeared emotional and uncomfortable to be asked about her upcoming stint in rehab by David Letterman on his CBS show.

Lohan faces a three month stay as part of a plea bargain in a traffic offence earlier in the year.

Letterman opened by asking, "Aren't you supposed to be in rehab now?" and continued to grill the actress on the topic, to her obvious dismay.

Lohan appeared increasingly alarmed as Letterman continued:

The troubled actress, who has been arrested on several occasions for a number of offences, said she was looking forward to being healthy and focusing on getting back her career back on track, but reprimanded Letterman for putting her on the spot.

After her appearance she tweeted her fans to thank them for their kind words of support.
