Phaedra Parks has reached her breaking point on being accused of cheating on her husband Apollo Nida.

Nida is currently serving an eight-year sentence in federal prison. He pleaded guilty to serious fraud charges including identity theft last year. Since then, he has accused Parks of cheating on him after he said he found inappropriate text messages in her phone with another man. While Parks calmly denied the rumors to Nida, she didn't take it so well when the accusations were coming from her arch nemesis Kenya Moore.

On Sunday night's episode of The Real Housewives of Atlanta, it was actually Cynthia Bailey who brought up the speculation.

Parks immediately got on the defense and said it was all a lie. While Bailey had to admit that she had never witnessed Parks with another man herself, she made it clear she thought there was some truth to the speculation.

Bailey added, "I'm just telling you what your husband said."

Parks then reminded Bailey, and the rest of the girls, that Nida also claimed Moore came on to him at one point. She asked if she was supposed to believe that was true now as well. That's when Moore jumped in and got into a spat with Parks. But Parks had enough and jumped up from her seat and lunged toward Moore. Thankfully she was able to stop herself before she hit her.

But that didn't stop Moore from talking. She said, "You need to check your husband."

Take a look.
