Actress Heather Locklear was rushed to a Los Angeles hospital yesterday after downing a dangerous mix of prescription pills and booze, according to officials. The 50-year-old Melrose Place actress was conscious when paramedics arrived and is responding well to treatment, sources told TMZ. Locklear was treated in 2008 for depression, and is now said to be distraught because she and actor Jack Wagner called off their pending marriage. (More Heather Locklear stories.)
