Kim Richards got some sisterly support from Kathy Hilton over dinner Wednesday at celebrity hotspot Mr. Chow in Beverly Hills.
It was the first public outing for Richards, 47, since she left rehab earlier in the week.
The Real Housewives of Beverly Hills star was seen smiling as she and her older sister, 52, exited the restaurant, looking happy and healthy after completing a 30-day program for treatment of alcohol abuse and other issues.
Richards’s Real Housewives costars recently filmed a reunion special, according to Bravo executive and on-air personality Andy Cohen, but Bravo wouldn’t confirm whether or not Richards participated.
