Kenya Moore and Marlo Hampton from the Atlanta Housewives got into a heated argument two days ago - at the launch party for Marlo's new line of hair.

Marlo threw a launch party for her new wig line - Her Hair Collection. She invited family and friends to the event, including Nene Leakes, Kandi Burress, Porsha Williams, Cynthia Bailey, Shamea and Yovanna.

Here are pics from the event:

Kenya - who was not invited - showed up to the event and immediately tried to destroy Marlo's night.

Kenya took the microphone, and during the event, began promoting her OWN line of hair:

Marlo immediately leaped up and tried to shut down the extremely rude Kenya. The two started arguing and - SNAPPING ON EACH OTHER in front of the entire crowd.

During the back and forth, MTO News learned that Marlo called Kenya's husband Marc a "rent-a-husband." She was suggesting that Kenya's long-distance marriage is fake, and that Marc is being paid to play the role of her husband. (Marc lives in NYC and Kenya and Brooklyn live in Atlanta).

Kenya snapped back at Marlo by asking if "Ted Turner was an investor in her wig line." Marlo is rumored to have been the longtime (and well paid) side chick to billionaire Ted Turner.

The incident nearly got violent, we're told - and the two ladies had to be physically separated. Our insider explained, "Marlo was ready to pop off on Kenya - luckily security stepped in before she was able to do it."
