Vicki Gunvalson and Shannon Beador used to be friends

Vicki Gunvalson and Shannon Beador struck up a friendship during The Real Housewives of Orange Countyseason 9 after Beador was brought to the show along with Lizzie Rovsek to replace Gretchen Rossi and Lydia McLaughlin, who left the show after its 8th season. However, during Season 10, Vicki Gunvalson had a falling out with Beador -- and the majority of her co-stars due to the controversy surrounding her former boyfriend Brooks Ayers' cancer diagnosis.During The Real Housewives of Orange County's 10th season, Gunvalson was accused of covering up her ex-boyfriend's alleged cancer lies by the majority of her co-stars, including Meghan King Edmonds, Heather Dubrow, Shannon Beador and Tamra Barney.

Vicki Gunvalson and Brooks Ayers ended their relationship last year

Gunvalson's relationship with Ayers was frowned upon by her friends and family for years and in August of last year, amid allegations claiming Ayers had faked his cancer diagnosis, they called it quits. Unfortunately, the drama surrounding Ayers' cancer has lived on and many of her co-stars still feel that she knew much more about Ayers' reported lies than she has revealed thus far.
