It eventually got so bad that one of Behar's remarks to Jones was bleeped - and Jones called Behar a "b***h" before being cut off the air.
The brouhaha started when Jones called into the show to talk about her recent elective surgery, a breast lift, and rumors she was near death after receiving a blood transfusion following the procedure.
"Can we first start with the fact that I did not almost die?" said Jones. "You guys know I'm anemic . . . when you have surgery, you have to make sure your doctors know everything going on . . . just in case I needed some blood, which I did . . . Literally, I was fine right afterwards."
Behar appeared to grow increasingly irritated as Jones kept talking about her surgery, answering questions about it from her co-hosts. "It's a little bit of a hoist because after you lose some weight, you sometimes go real flat, and I really wanted to lift them up," she said of her breast lift, which included implants.
At one point, as Jones kept talking, Behar grabbed a pen and furiously scribbled a note, then gestured to Meredith Vieira to read the note, tapping the paper for emphasis.
"Last Friday was my 44th birthday, but my boobs still think they're 20," Jones said - and that's when Behar heard enough. "OK, Star. That's enough about you. On to us. 'Bye," she snapped.
Behar was bleeped when she added "Keep your [breasts] perky!" in a mock-cheerful voice.
"I'm glad to see you haven't changed," Jones shot back. "Even today, you are still a b***h," she said before the call was abruptly cut off.
"If you watch 'The View' regularly, Star and Joy enjoy teasing each other. No harm done," said a show spokesman. "There's no reason to read any more into it than what was on-air."
This was, however, the latest in a long line of Jones-Behar dustups. Last December, the two went at it during a discussion of religion, when Jones began talking about her "personal relationship with God" - and Behar wondered aloud why this "is a public thing."
Last January, Jones said on "The View" that the war on terror was simply a clash of male egos between President Bush and Usama bin Laden.
