The sister we all loved to hate Lori (Lisa Robin Kelly) of the beloved sitcom "That 70's Show) has passed at the age of 43. We have known for sometime tha Lisa struggled terribly with the disease of addiction.

TMZ is reporting that Kelly died in her sleep on Wednesday (Aug. 14) while attending a rehab facility in California.

She was brought in by her current boyfriend on Monday night but went into cardiac arrest two days later.

Close sources are saying:

“She had been fighting demons for a while and finally lost her battle.”

After years of drug abuse, DUI's and Spousal abuse may she now finally rest in peace. Thanks for the memories Lisa...
