The troubled actress, who has a history of drug and alcohol problems, was rushed to a suburban Los Angeles hospital after her worried sister rang for help.
As RadarOnline.com exclusively reported, Heather had been taking Xanax and had been drinking heavily when Colleen intervened.
Less than 48 hours earlier, Heather was visibly intoxicated when she sat courtside at a Laker’s game.

“Heather becomes a different person on drugs,” the source told ET, adding that her on-again-off-again relationship with former fiancé Jack Wagner has been particularly tough for her to handle. The fact that he’s sober and she’s not was the cause of their latest break-up.
Locklear’s daughter Ava is now staying with her father, Heather’s ex-husband Richie Sambora.
The actress was released from Los Robles Hospital and Medical Center late Friday.
“She is in no danger and she’s going to be just fine,” her parents Bill and Diane Locklear said in a statement.
