Kathy Griffin is in trouble once again. The Irish American comedienne dropped the F-bomb on Anderson Cooper's program on New Year's eve on CNN.

Griffin was co-hosting "New Year's Eve Live With Anderson Cooper and Kathy Griffin."

Griffin and Cooper were discussing the balloon boy case when Griffin intentionally mispronounced Falcon Heene's name.

"Fal-- Fuckin? Falcon? How do you say it?" Griffin asked Cooper .

Cooper shook his head and smiled. "You're terrible. Really terrible."

Griffin is known for her no-holds barred approach on live television. Parts of her shows are often bleeped out even on cable because of bad language.

Kathy Griffin: What does that F stand for anyway Kathy?!
