It looks like Brooks Ayers doesn't have anyone on his team, especially not his girlfriend's daughter. Vicki Gunvalson's adult daughter, Briana Culberson, opens up about how she really feels about her mom's boyfriend in the upcoming episode of Bravo's "The Real Housewives of Orange County."

In a sneak peek for episode 18 of "RHOC," Culberson is out for lunch with her mom's BFF and co-star Tamra Judge. Judge explains to Culberson that her mother pulled her aside during the ladies' trip to Tahiti and asked Judge to speak with Culberson about Ayers.

"Ugh, this is like the never-ending story," says Culberson. "I've tried too and, like, I'm not gonna bring him up anymore with her. If I have anything to do about it, I never want to see him for the rest of my life. He's done."

Culberson and Gunvalson got into a heated argument about Ayers in a previous episode. As a nurse, Culberson found it strange that her mother's boyfriend went away on business even though he was recently diagnosed with stage three cancer. Culberson is yet another person who thinks Ayers is faking his diagnosis, which adds to the fact that Culberson never approved of Ayers in the first place.

"There is absolutely nothing Brooks can do for me to accept him or to move past anything or to forget anything or to forgive anything because he has proven his character," says Culberson in her on-camera interview. "And all I care about is my mom."
