Forget the D-List!

Comic Kathy Griffin rang in 2010 by dropping the F-bomb live on TV during CNN's New Year's Eve broadcast with anchor Anderson Cooper Thursday.

Just before midnight, Griffin and Cooper were discussing 2009's top news stories, including the October scandal involving Colorado's Richard Heene, who hatched a hoax that his 6-year-old son, Falcon, had floated away in a homemade helium balloon. (Watch a clip above)

"Fal ... Fu--ing? Falcon? How do you say it?" Griffin asked Cooper during the broadcast, fumbling the boy's name.

The chuckling anchor's response? "You're terrible," he told Griffin, who was warned not to curse on TV. "Really terrible."
