David Letterman 'Apologizes' to Lindsay Lohan After Being 'Duped'

David Letterman got big laughs on his show Wednesday night after directing a comment to Lindsay Lohan, saying he needed to "apologize" to her.

Earlier in the day, a spokesperson for CBS' Late Show With David Letterman issued a statement saying that Lohan would not be appearing on the show, as previously announced, to deliver a Top 10 list.

"We made a mistake," the statement read. "Someone purporting to be a friend of Lindsay's reached out to the show yesterday, allegedly on her behalf, and booked her to appear. Clearly, this person was not authorized to make commitments on her behalf. We wish Lindsay well, and look forward to having her on the show in the future."

Theactress also chimed in via Twitter. "I am NOT going to be doing David Letterman, I'm not sure how this happened, but I am sorry for the confusion...," she wrote.

(Lohan's father later came forward to say he was responsible for the booking.)

On his show Wednesday night, Letterman explained to his audience how the whole thing happened, starting with his joke at Sunday's Grammy Awards in his Top 10 Grammy Surprises list: "Lindsay Lohan seen leaving Staples Center with Grammy-shaped bulge in her jacket," he quipped.

"The next day I get a call and it's a guy and he says, 'Lindsay thought the joke was hilarious.' Now you know Lindsay is gonna stand trial for stealing stuff. So the guy says, 'Lindsay thought that joke was hilarious, she wants to be on your show,' and I said, 'Great, great!' " Letterman said, slapping his hand on his desk for emphasis.

He immediately called his PR department and asked them to get a press release out right away.

"It goes around the world," Letterman said. "People are just, are you kidding me? This is gonna be fantastic, this is gonna be like the Super Bowl. ... And then Lindsay Lohan says, oh, you know none of that's happening. It turns out we were duped. And I have no one to blame but myself, and boy is my face red."

With his trademark sarcastic wit, Letterman then delivered his "apology" to Lohan.

"And by the way, now I need to apologize to the Lindsay Lohan family," he said. "I hope I didn't embarrass you, Lindsay, or your family."
