AceShowbiz - Kathy Griffin delivered a New Year's surprise to the crowd in New York's Times Square and many viewers at home during CNN's New Year's Eve Show on December 31, 2011. The "Pulp Fiction" star stunned everyone, including her co-host Anderson Cooper by stripping down to her bra and underwear.

"Oh, my Lord," Anderson first exclaimed as the camera panned back, revealing Kathy’s new look. "Are you frickin’ kidding me," Anderson asked multiple times before telling viewers that he didn’t know she was planning to remove her clothes. Kathy tried to explain the prank by comparing her skimpy state to the event’s performer Lady GaGa. "I was inspired," she insisted. However, Anderson wasn’t having it and held up a "No Nudity" sign while Kathy argued that she wasn’t nude and called the broadcaster a "big square who won’t let me have any fun."
