Lindsay Lohan probably thought she was in for a soft-ball interview when she swung by the Good Morning America set this morning to talk about her new Lifetime movie.

What occurred, however, was a nervous-chatting sit-down held in a nightmare chamber of horrors.

As you can see from the clip above, things go awry pretty much immediately, when GMA's Amy Robach blurts out the just-released news that Lindsay Lohan has a surprise half-sister (the product of an affair her father had with a woman twelve years ago), which Lindsay claims not to have heard previously:

"I didn't even hear that, so thanks for the news. I don't lis—I don't pay attention to any of it."

Later in the interview, Lindsay's answer to a question about wigs is interrupted by a miserable baby wailing off screen. (The babies were brought in for a weird segment that involved them smashing cakes with their hands; most of them just stared at the cake their parents forced into their hands and cried.) This, Lindsay apologizes, causes her to become "sidetracked."

Other parts of the interview that cause Lindsay to become sidetracked include: her realization that GMA has footage of her in her Liz Taylor wig ("Ohmygod, there's footage"), her realization that GMA has footage of her [as an established child actress] at age 12 ("so funny"), and the moment when GMA plays her segment to commercial, using her 2004 single "Rumors" ("Ohmygod").
