Kenya Moore denies that a brawl broke out between her and her "Real Housewives of Atlanta" co-star Porsha Stewart during a taping of the show.

According to People magazine, the feuding stars got into a physical altercation during the taping of the show's reunion episode on Thursday.

"A fight broke out that had to be broken up," a source was quoted telling the magazine.

The source added that there was "definitely some hair pulling" though no one was injured and the fight was broken up quickly.

But a rep for Moore told ABC News, "Miss Moore was not engaged in any physical altercation. She adamantly condones violence and would never be involved in such behavior."

Moore also tweeted earlier today, "one thing u will NEVER see me do is fight. Your brain and tongue are your most powerful weapons."

How Porsha Stewart Learned about her Divorce from Kordell Stewart

Since meeting at the star of Season 5, Moore, a former Miss USA, and Stewart have been engaged in a war-of-words.

During a heated argument over Stewart's failed marriage to former NFL quarterback Kordell Stewart, Moore called Porsha the athlete's "beard" and said their marriage was nothing more than a PR stunt.

"Porsha sounds like a broke down Olivia Pope," Moore said on the show. "This isn't 'Scandal.' Just stop faking it."

For her part, Stewart has referred to Moore as "the ring leader for anything that will create drama," on her Bravo blog.
