Call off the feud.
Kathy Griffin swears she didn't slam Stephen Colbert, 45, on Twitter after he beat her out for the best comedy album Grammy. (His Colbert Christmas: The Greatest Gift of All! was up against her Suckin' It For the Holidays.)
On Sunday, a message was posted -- and widely picked up by blogs -- on a Twitter page the comic, 49, says she no longer uses, "Stephen Colbert STOLE my mother f-ing Grammy!!"
Wrote Griffin on her real account Monday night, "OMG, I feel like Miley Cyrus. My old Twitter acct was hacked...I did NOT diss Colbert re Grammys."
The Disney star's account was hacked in February 2009. She deleted it a few months later.
