Kim Richards in rehab; 'Real Housewives of Beverly Hills' star seeking help for addiction

Kim Richards, one of two Richards sisters who star in Bravo's "Real Housewives of Beverly Hills," has entered rehab, reports ETonline.

The 47-year-old is reportedly seeking help at an undisclosed treatment center.

Richards' drinking has been a frequent topic of conversation -- and documentation -- on "RHOBH." On last season's finale sister Kyle Richards accused Kim of being an alcoholic. Kim's family subsequently checked her into rehab, but she checked herself out a week later.

This season, new castmate Brandi Glanville accused Kim of being "wasted out of her f***ing mind" during one episode. In another, Richards admitted to taking anti-anxiety medication and anti-depressants.
