O'Brien has recorded herself over the months impersonating numerous different celebrities, including Taylor Swift, Angelina Jolie, Katie Holmes, the Olsen twins, Kim Kardashian, Ellen DeGeneres, Sofia Vergara, Mindy Kaling, Drew Barrymore, Anne Hathaway and even fictional characters like Lois Griffin.
But the impressions weren't all flattering.
O'Brien's Kristen Stewart impression was nothing but "ugh"s from the actress, accompanied by blowing hair out of her face. For Lena Dunham, she showed up in the back of a car with no clothes on.
"Maybe I should have taken the subway instead of a cab," O'Brien said as Dunham. "And then, I don't know, part of me feels like I should have put some clothes on before I left."
As Drew Barrymore, she mentioned her "new Adam Sandler movie."
As Taylor Swift, she sang to her own music in the car, and as Angelina Jolie, she was listening to Whitney Houston and being deep about life.
O'Brien not only did spot-on impersonations of the celebrities, but she also managed to look pretty much like most of them.
