Following the season 7 premiere of Real Housewives of Beverly Hills, In Touch has exclusively learned that one series cast member will be forced to come clean about her drug addiction this season.

A source revealed to In Touch that the cast member — either Eileen Davidson, Erika Girardi, Dorit Kemsley, Kyle Richards, Lisa Rinna, Eden Sassoon, or Lisa Vanderpump — is approached on camera by her co-stars, as they believe she's been abusing Xanax.

Kyle's sister Kim Richards, who was a former cast member on the series, previously opened up about her drug use with Dr. Phil. In addition to taking unprescribed pain killers, she admitted she smokes marijuana "every once in a while."
