Vicki Gunvalson has been battling her daughter, Briana, for quite a while now over the man who was, until recently, her beau. Now, Gunvalson has broken things off with Brooks Ayers, and she and Briana sat down with Andy Cohen for an interview about why things went south and what Ayers did behind Vicki’s back.

Briana told her mother long ago that Brooks was a dirty dog, saying he pulled her aside at Vicki’s birthday party and hit on her (while she was pregnant, no less). He also reportedly told Briana he wanted to show her what he’s packing and told her his nickname is “Girth Brooks”.

“And I told her that he did (make a move) and she called me a liar and said that he would never want me,” Briana said. “This guy’s a piece of sh*t,” Briana said during the sit-down.

She and Vicki have had a rough time lately over Brooks, who Briana says has been lying about having cancer amongst other things. However, Vicki didn’t want to believe the nasty stories about her man and refused to break things off with him for a long time.

“I didn’t want to believe it was even truth,” Vicki Gunvalson said.

Briana has maintained for years now that she believes Ayers is lying about having stage 3 non-Hodgkins lymphoma, but Vicki brushed her worries aside, which caused a rift between the two of them. Ayers said earlier this year that he thinks Briana and the other women of The Real Housewives of Orange County are just seeking attention.

“I think they do it to create drama. It’s useless drama that brings on stress that quite frankly no one needs and in particular my situation. I’m not running from anything,” Ayers said.

The second half of the reunion special will air on Bravo on Sunday at 8 p.m.
