When Heather Locklear was rushed to the hospital on Jan. 12 after mixing alcohol and Xanax, many speculated whether the "Melrose Place" actress would return to rehab for a third time. But according to a source close the family, that is not the plan.

Instead, the 50-year-old actress has resumed the ongoing sobriety program she began and maintained in 2011 until the difficult split with her fiance, actor Jack Wagner. Locklear will work with doctors who will monitor her progress, and she will also continue to be tested monthly for drugs and alcohol. The family is also receiving additional support from UCLA to help with the anxiety caused by the breakup.

According to the source, Locklear had not had a drink for months. But her split with fiance Jack Wagner in November and receiving numerous bottles of wine as gifts for Christmas led her to fall off the wagon. At the time of her hospitalization, Heather was "menopausal, depressed and dealing with a great deal of anxiety of a recent breakup," said the source. "When her sister suspected something was wrong, she didn't mess around and called 911."

Though she was the one who called off the 3-month engagement to longtime beau Wagner, she was still struggling with it in January.  According to our source, Locklear, who has been married twice before, decided she didn't want to walk down the aisle again. But Wagner did, which caused big disagreements between the couple until she finally ended it.

Locklear's previous issues with depression and substance abuse and her family's history of alcoholism led her to voluntarily turn to experts at UCLA for support. She's reportedly back to her daily 90-minute workout routines and also doing therapy to address the breakup and anxiety associated with it.
