On Saturday night's CNN New Year's Eve broadcast, comedienne Kathy Griffin, who co-hosted live coverage of the Times Square ball drop with Anderson Cooper, stripped down to her bra and panties, startling Cooper and sending him into a fit of giggles (video below).
"Are you freaking kidding me?" Cooper asked. The 'shocked' CNN anchor then waved a (prepared) 'No Nudity' sign in Griffin's face.
Griffin refused to get dressed, instead waving to party-goers in Times Square and flirting with CNN contributor and former presidential adviser David Gergen.
"You're a big square who won't let me have any fun," Griffin taunted a nervous Cooper, trying to get him to follow suit. "Your turn!"
After Cooper cut to CNN correspondent Gary Tuchman and his 14-year-old daughter in Central Park, Griffin finally got dressed, much to the relief of television viewers around the world.
