Rosie O'Donnell Calls Elisabeth Hasselbeck a "Twat"

Hey. At least Elisabeth has a twat. Keep it classy Rosie.

It all happened on August 5 during a stand-up routine as part of O'Donnell's "Girls' Night Out Tour" with singer Cyndi Lauper. First, Rosie cracked jokes about "The View," illiciting roars of laughter from the audience at the St. George Theatre in Staten Island, N.Y.

"Rosie started out by asking the audience, 'What was that show I was on?'" an audience member tells FOX411. "Then, instead of saying, 'The View,' she called it 'The Screw You.' She continued by calling Elisabeth Hasselbeck, 'Elizabeth Half-a-brain.' Then she jumped to another topic."

But Rosie wasn't done. Not even close.

The audience member says she went back to her "The View" experience. "Rosie said when she first met Elisabeth, she thought she would love her, because they're both Christians," the eyewitness says. "Then she stopped and said, 'But then she turned on me.' Then Rosie called her a 't--t.' O'Donnell then moved on to a different subject, saying she really didn't want to start a new feud, or restart an old one."
