"The Real Housewives of Orange County" is about to get more fierce for Shannon Beador and Vicki Gunvalson in season 11. Vicki claims to know about a big secret that Shannon is desperate to keep quiet, but will expose it if she feels provoked enough.

'Watch in two weeks,' Shannon tweets.

According to a tweet posted by Shannon Beador, things are going to get worse between she and Vicki Gunvalson before the season is over. A fan cautioned Shannon that she shouldn't cozy up to Vicki because she'll bite harder next time.

Beador responded by writing Vicki does bite harder -- more than ever. She wrote that what unfolds is "disgusting" and that viewers will have to wait and see what happens in two weeks.

It sounds like one of the ugliest of disputes between Vicki and Shannon on "The Real Housewives of Orange County" will happen in episode 16. Will Shannon's big secret come out then?

Vicki said in her confessional interview on the latest "RHOC" episode that Shannon has a secret so damaging, it will hurt her family. Whatever the secret is, it involves Shannon's marriage to David.

Shannon claims Vicki is lying, but Vicki insists she was told something in confidence by Shannon that she wouldn't expose unless she feels maligned by her.

Shannon desperate to keep secret quiet?

At the end of the latest episode, Beador was trying to be friendly with Gunvalson at Heather Dubrow's party. The other women were dismayed by Shannon suddenly laughing and talking to Vicki. The last time they were together, they made a scene at Meghan's party.

Shannon making nice with Vicki set off red flags for a number of fans. Some wonder if Shannon did it because she does have a secret and is protecting it by trying to be on good terms with Vicki. It's possible, but it's clear as mud what the truth really is. Beador claimed she was being nice to Gunvalson because she wanted to prove to the other women that she was able to move on.

If there is a secret that Gunvalson leaks about Beador this season on "The Real Housewives of Orange County," will it hurt her family?

She and David are together and happy. Everyone is anxious to find out what Vicki is holding over Shannon.
