Heather Locklear Rehab Standoff With Family

1/18/2012 4:00 PM PST
Heather Locklear is digging in her heels ... continuing to defy family members who are pleading with her to check into a rehab program.

Sources tell us Heather is recovering at home after a dangerous mixture of prescription pills and booze landed her in the ICU last week with intense stomach pains.  But family ... including Heather's parents ... are still pushing for her to get professional help.

As TMZ first reported -- Heather's family is pushing for her to get treatment at UCLA Medical Center.

So far, Heather's not budging.
