Brooks Ayers fiercely denies hitting on his ex Vicki Gunvalson‘s daughter Briana Culberson.

The Real Housewives of Orange County drama played out on Monday night’s second installment of the three-part reunion, when Culberson shockingly alleged Ayers came on to her at her mother’s birthday party. Culberson said she was pregnant when Ayers offered to show her his penis.

Ayers is now defending himself against the claims.

“It’s a typical Briana move, creating a ‘He said, She said’ scenario that once again puts her mother in the middle of a no-win situation,” Brooks told E! News. “I’m glad that I no longer have to deal with this unnecessary drama. I categorically deny having said anything like that to Briana.”

Gunvalson, 53, and Ayers announced their split in August.

Gunvalson, who previously did not believe Culberson and accused her daughter of lying, said during the reunion episode that she now believed her daughter about the alleged birthday incident.

On Monday’s episode, Andy Cohen played an interview he’d taped with Ayers in advance the RHOC reunion. During the one-on-one, Ayers accused Culberson of manipulating her mother and relying on her for financial support. Culberson couldn’t contain her anger and called Ayers a “filthy piece of s—.”

Ayers and Culberson have long had a strained relationship, and Ayers slammed Culberson in an interview with E! earlier this month, claiming she “had some significant issues as a child growing up, some quote unquote ‘daddy issues.’ ”
