'RHOC' Reunion: Vicki Gunvalson's Briana Hears Brooks Ayers Call Her A 'Manipulator,' Shannon Beador Says She Has Proof Of Cancer Lie And Tamra Judge Hears From Alexis Bellino

Bravo has released a preview of the upcoming three-part The Real Housewives of Orange County season 10 reunion show. Not surprisingly, the preview shows that much of the reunion will focus on whether Brooks Ayers and Vicki Gunvalson lied about him having cancer, as the rest of the cast seems to believe. Some of the more explosive moments that viewers will see may be when Vicki's daughter, Briana Culberson, joins her on the couch and hears Brooks call her a "manipulator." Shannon Beador also confronts Vicki about telling her friend about David Beador's affair when she was supposed to keep it a secret and reveals that she has proof that Brooks is lying about having cancer. The preview also shows that a former cast member, Alexis Bellino, will have a presence on the reunion.

The preview for the reunion shows that Briana, wearing a purple sheath dress, sat next to her mom for at least part of the reunion. As previously reported by the Inquisitr, host Andy Cohen taped an hour-long interview with Brooks to get his side of the story. The interview took place prior to his filming the reunion show with the housewives and will be aired during the reunion.

Since Briana has been a very vocal critic of Brooks, it may come as no surprise that Andy, during his interview with Brooks, brought up Briana to Brooks. Viewers will apparently see Brooks call Briana a liar, since Andy is shown asking Brooks what he thinks is Briana's motivation to lie about him. "Manipulation," he replies.

The preview then cuts to a very angry Briana giving the camera her middle fingers.

On last week's episode, Briana was shown telling Tamra that Brooks once claimed to have pancreatic cancer. Briana said that after much questioning from her, he finally admitted that he only had pancreatitis, an inflammation of the pancreas.

Vicki and Brooks announced their split in August so they were already broken up for some time when the reunion filmed earlier this month. Despite the breakup, will viewers see Vicki become defensive over Brooks and lash out at her daughter? On Monday night's season finale episode, Vicki told Tamra, after Tamra pointed out that Briana has revealed that Brooks lied about having cancer in the past, that Briana is a "s**t stirrer" who wants to destroy Brooks.

Or perhaps, in a departure from the past, Vicki Gunvalson will finally agree with Briana Culberson that Brooks Ayers is not as good as she thought he was? As the Inquisitr reported, Vicki said on the Sunday after filming the reunion show that she's "somewhat disappointed" that Brooks did an interview with Andy and that she's completely done with him.

As expected, the preview also shows the other housewives criticizing and questioning Vicki. Shannon Beador yells at Vicki for telling her brother's girlfriend, Rhonda, that David cheated on her. On the season finale episode, Rhonda, in an attempt to defend Vicki, told Shannon during Tamra's baptism party that Vicki didn't ask to see the records when she thought her husband was cheating on her. Shannon, who maintains that Vicki knew at the time of filming the party that she was supposed to keep David's cheating a secret, blasted Vicki for betraying her trust.

On the reunion show, Shannon accuses Vicki of having no remorse.
"It's all okay Vicki! No remorse from you!
In one moment, Vicki seems to try to distance herself from the Brooks cancer drama as much as possible by feigning ignorance.
"I don't have any proof that he's not faking cancer and I don't have any proof that he is."
At that moment, Shannon chimes up. "I do," she says.

Heather Dubrow accuses Vicki of knowing that Brooks was lying with cancer but continuing to lie to them about it.

"We're all agreeing on this. The only question for me is, when did you find out?"
In a heart-to-heart moment between Vicki and Tamra, during what seems to be during a break that's still being filmed, Tamra advises Vicki to fess up. Vicki, having gone up from her couch to sit next to Tamra, looks downcast as Tamra gently tells her to admit to her mistake.
"I knew he was a s**t the day you started dating him. But now's your time to say, 'He lied to me.'"
Even Andy grills Vicki. After saying that Vicki has admitted to fabricating a story, he asks Vicki what else she has lied about.

Thankfully for her, Vicki Gunvalson isn't the only housewife in hot seat on The Real Housewives of Orange County season 10 reunion show. The preview also shows Shannon Beador answering why she thinks David Beador cheated on her. Tamra Judge is also told by Andy Cohen that former co-star Alexis Bellino, whom she once called "Jesus Jugs" at a reunion show, has something to say to her.

"I got an e-mail from Alexis, 'Jesus Jugs,'" says Andy. "Shocker!" replies Tamra.
