Tori Spelling's no so innocent after all.

The reality star — who’s in the limelight for her show True Tori, which will show her trying to salvage her marriage in the wake of husband Dean McDermott’s admitted cheating and subsequent stint in rehab — has been abusing powerful painkillers, according to a Spelling insider.

“I have seen huge bottles of Vicodin and Oxycodone while I was visiting her,” the friend told STAR magazine, delving into detail as to how deep the reality star is into the Opiate-based medication.

“Once I saw her at lunch, popping Vicodin with wine — which you shouldn’t do; once she offered me a Vicodin when we were all out to dinner and when I passed, she offered me a Norco that was even stronger than the Vicodin!”

The source -- who passed a lie detector to prove their claims -- said that Spelling claims she takes the drugs to handle her migraines, but pointed out that her behavior doesn’t square with that approach.
