Gizelle Bryant faces some harsh payback when she's excluded from Monique Samuels’ lake house summer soirée on Sunday night's episode of "The Real Housewives of Potomac."

"We're just not meshing," Monique said to Gizelle in TooFab's exclusive clip (above). "I wanna get to know you, you get to know me, and then if you don't like me at the end of the day, that's fine. I just want to see what the problem is."

Gizelle choked upon attempting to respond to Monique, which Monique felt was God's way of keeping her from spewing lies.

"You about to tell a lie and you choked on that lie," Monique said while reflecting on the awkward confrontation. "God is like, 'I don't like when people tell lies,' so he just choked her right from the start. She didn't get a word out."

When Monique called Gizelle out for being judgmental the day she hosted the women at her home, Gizelle interrupted to say she had already apologized for that.

"I heard you, but I was not feeling you," Monique said.

Gizelle then brought up the time Monique called her a "stuck-up trick," which Monique explained means "childish."

"I wanted to apologize to you, which is why I asked for your phone number at Karen's event," Monique explained, which ignited another debate about whether Monique asked Gizelle for her number or told Gizelle to give her her number.
