“Have you had any sexual communications with other women?” the administrator of the test asked Baier.

Portwood then screamed, “I’m about to freak out, I’m about to freak out!”

In another clip, Portwood says, “I told him if he ever cheats on me I’ll leave.”

The trailer then cuts to a man holding Portwood as she tries to attack Baier while screaming, ‘You f**king b***h!”

On last week’s episode, Portwood learned that Baier has been texting another woman.

“There’s fake f*****g text messages supposedly,” Portwood said of messages that emerged between Baier and another woman on social media. “Talking to someone else like a year and a half ago. I told him in the car we need a break. This is too much. It just keeps making me doubt everything. I need to figure out what’s going on with all this s**t.”
