According to a source, the troubled actress left a Los Angeles based treatment center on Saturday, May 25.
The former Melrose Place star landed herself back in treatment early last month after an ugly spat with Heisser, her high school sweetheart whom she reunited with 2017.
The couple, who have a history of fiery flare-ups, squared off in late April, sources said.
“Heather and Chris got into a screaming match, and after they finally cooled down she realized she’d lost control again and decided she needed to head back to rehab!” a snitch spilled at the time.
As Radar readers know, Locklear, 57, hurled vulgar insults at cops and swigged tequila before she was committed for a 72-hour stay at a psych ward on November 18, 2018 — which was then extended for another 14 days!
Locklear was also hauled off to a psych ward last June and was facing charges for battery on a police officer, along with resisting arrest after cops tried to break up another dispute with Heisser in February.
