Fights, Feuds & Freakouts! 'Real Housewives Of Orange County' Season 11 Secrets Revealed

Season 11 of Bravo's flagship housewives series, The Real Housewives of Orange County, has started filming and RadarOnline.com has learned it is already jam-packed with serious drama! According to multiple sources, the contracts have been signed and the show is already filming in several secret locations. Click through these seven photos as RadarOnline.com exclusively reveals who is in and who is out!

Vicki Gunvalson, 53, got into a war with her other cast mates – Shannon Beador, 51, Tamra Barney, 48, Heather Dubrow, 47, and Meghan Edmonds, 31 – last season over her involvement in then-boyfriend Brooks Ayers's cancer scandal. Gunvalson claimed that she had no idea that Ayers had lied about his cancer battle.

Gunvalson split with Ayers following the end of last season, but she and former BFF Beador grew apart then too. As previously reported, Beador slammed Gunvalson and accused her of lying to cover up Ayers's fraudulent cancer claims.

According to several sources, the answer is yes! "Vicki and Shannon are both back on the show for this upcoming season," a well-connected source told RadarOnline.com. "They have already been going at it about the Brooks cancer drama that happened last season and neither one of them is backing down to each other."

Although numerous outlets have reported that Bronwyn Jones – a successful model and actress – would be joining the cast full-time, a separate source told RadarOnline.com that is not the case! "Bronwyn has been filming with them and it is still undecided on whether or not she will join the cast full-time," the insider said.

But what about the other ladies? RadarOnline.com has learned that all five of the cast members from last season are returning! Yes that means that Gunvalson, Beador, Dubrow, Barney and Edmonds are all coming back to the OC and bringing with them all of their baggage from last season! "The contracts have been signed and they are all back on board," said the source.
