Heather Locklear -- Family Wants Treatment at UCLA Hospital

Heather Locklear is out of the hospital, but we've learned her family wants her back in -- at UCLA Hospital.

As we first reported, Heather went to rehab last October in her battle with prescription drug addiction ... and it wasn't her first time.

Sources tell us the family wants her in a hospital setting this time around -- not a boutique rehab place -- and UCLA has one of the best facilities in the country.

You may recall, Lindsay Lohan spent time at UCLA's Stewart and Lynn Reskick Neuropsychiatric Hospital in August 2010, but she was released early.
