Brandi Glanville got a bit too relaxed on their mini vacation to Palm Springs, first, admitting to using cocaine and then picking a massive fight with newbie Joyce Giraud on Monday night’s episode of The Real Housewives Of Beverly Hills.

Heading to the girls' bonding trip, Brandi shocked Yolanda Foster, dropping a bombshell about her past drug use.

“The first time I was ever in Palm Springs was the first time I ever did the Master Cleanse,” Yolanda shared in the limo. Brandi countered her story and bluntly revealed: “And it was the first time I did cocaine.”
