Someone from Lohan's camp reportedly reached out to the show and booked Lindsay to announce the "Top Ten" segment via satellite for Thursday's show, according to Reuters. "We made a mistake. Someone purporting to be a friend of Lindsay's reached out to the show yesterday, allegedly on her behalf, and booked her to appear," explained a spokesman for the show.
Clearing things up on Twitter, the actress wrote, "I am NOT going to be doing David Letterman, I'm not sure how this happened, but I am sorry for the confusion."
Both parties are not sure who was responsible for the mixup.
