Real Housewives of Atlanta star Nene Leakes is being accused of cheating on her husband Gregg Leakes - by Youtube talk show host and former female rapper, Khia.

According to Khia, she has seen "pictures" of Nene cheating on Gregg with an "older White man."

Khia made the explosive claims in a video that she published last night. In the video, she called Nene a "moose on the loose" - because of the reality stars alleged cheating.

Khia also claims that Nene's new side dude is associated in some way with former Atlanta Housewife Kim Zolciak-Biermann. Unfortunately Khia wasn't very specific about how Kim and the alleged side dude know each other.

Khia, who is also living in Atlanta, claims that Nene is making a mistake by cheating on Gregg. The former female rapper told fans, "Gregg was your number one customer when you were dancing on that pole." Nene met Gregg when she worked as a stripper 20 years ago.

She continued, "Gregg left his family and his children for you [Nene], it makes no sense for you to try and leave Gregg."

Here's an excerpt of Khia talking about Nene.
