What happened between Porsha Williams and Kenya Moore during RHOA reunion taping?

UDPATE: March 31. TMZ procured the 911 call Moore made about the attack requesting cop assistance. Try to refrain from laughing.

Resident instigator Kenya has been goading Porsha into a confrontation in recent episodes over Porsha's divorce with Kordell Stewart. These episodes were taped several months ago.

On the show, Kenya has been calling Porsha out for her supposed "arranged marriage" and her role as the "beard" for her husband. (Kordell has flat out denied he is gay.)

Porsha and Kordell divorced last year after a two-year marriage.

The six women taped the reunion show Thursday in Atlanta in a 19-hour marathon that didn't end until after 1 a.m.. The episodes, which are typically spread over three weeks, air on Bravo in a month. (There are three more regular episodes of season six left to air.)

Porsha has gotten verbally angry on the show, this past Sunday calling Kenya a liar and saying she doesn't understand marriage because she has never had a husband.

Various websites and my source said Porsha during the taping attacked Kenya and pulled her hair. (If true, she is taking the Sheree Whitfield path of physical confrontation. Remember when she "pulled" Kim Zolciak's wig?) Kenya reportedly brought a scepter on set, as if she's "royalty." She also used a bullhorn as a prop. Kenya threw out unverified rumors that Porsha cheated on Kenya, then invited Porsha to hit her so she could get Porsha fired, my source said.

Porsha apparently fell for Kenya's bait and went after her aggressively, but security pulled them apart relatively quickly. None of the other ladies got involved. Kenya for a time didn't want to be in the same room as Porsha and as she had threatened, she demanded Porsha be fired, my source said.

The show itself is hitting ratings heights this season, averaging close to 4 million viewers a week catching it live and millions more in repeats. Certainly, Bravo will play up any physical confrontations in its trailers in a bid to boost ratings even more.
