Fantastic." PHOTOS: Celebrity rehab centers A former Disney child star, Kim, 47, briefly entered rehab in mid-2010, but declined to elaborate on her addiction issues. On Housewives' first season, a seemingly intoxicated Kim famously sparred with Kyle, 42, after Kyle called her an "alcoholic" during an ugly brawl.
