Tamra Barney has faced backlash throughout season 10 of The Real Housewives of Orange County due to her questions about Brooks Ayers' cancer and friendship with Meghan King Edmonds.

Tamra Barney Meets With Her Pastor To Discuss Baptism During 'RHOC' Sneak Peek

For years, Barney was a close friend of Gunvalson, so when fans saw her cozy up to Edmonds, who has been hateful towards Gunvalson all season, many accused her of being a bad friend.

In addition to calling Gunvalson an "old woman" who was "bitter at the world," Edmonds proclaimed her now-ex-boyfriend, Ayers, was lying about his diagnosis, and even called his doctors and ex-girlfriend in hopes of gaining damning information.

During season 10, fans watched as Barney admitted to knowing of what Edmonds had done, and doing nothing. In response, Gunvalson told Barney she was not her friend, and slammed her for not supporting her throughout her co-stars' allegations. However, Barney felt something was off, and encouraged Gunvalson to be sure of Ayers' claims.
