In 2008, Laurer -- better known by her wrestling name Chyna -- appeared on the VH1 reality TV show, Celebrity Rehab with Dr. Drew, where she was open about her issues with depression, and using drugs and alcohol. However, she strongly denied using steroids, and being an addict.

Dr. Drew Pinsky commented on Laurer's death on Thursday.

"I am very sad for Joanie and her loved ones, but I am also terribly angry because I suspect addiction may have taken another life," Pinsky told ET in a statement.

Redondo Beach Police said they found Laurer dead in her apartment on Wednesday, after receiving a 911 call from her friend reporting that she wasn't breathing. The friend told police that Laurer had not answered her phone in a few days. According to police, from the preliminary investigation, it appears Laurer died prior to being discovered by her friend. There are no indications or signs that the death was a result of foul play.

Laurer was 45 years old.
