During the latest episode of The Real Housewives of Orange County, Heather Dubrow and Shannon Beador were seen sitting down with Edmonds, who revealed she had called Ayers' doctor, pretending to have cancer.

"Wow. To pick up a phone and call Brooks' doctor to find out if he treats cancer patients that's going in... going in deep," Beador said in response to Edmonds' announcement. "It's a place I wouldn't go."

Edmonds, however, didn't feel she was out of line in contacting the physician.

"Guess what? People I love have cancer, and if you are going to fake that in order to get sympathy, or whatever you want, I'm going to get to the bottom of it any way I can, legally," Edmonds explained.
