To be honest, sweet little Heather Locklear is one of the last people we ever expected to land in rehab. But since her divorce from Richie Sambora her personal problems have escalated. According to the Enquirer, Heather didn't deliver herself to rehab to treat her "depression and anxiety" - she actually needed help with her addictions to alcohol, cocaine, and sleeping pills. On June 19 she checked into the Sierra Tucson clinic for treatment, but like Amy Winehouse , she checked OUT way too soon - on July 4! Her publicist says she's still in treatment somewhere - we hope it's true.
