Jodie Sweetin -- I Got a Hunch My Husband Started BS Rehab Rumor

Jodie Sweetin's estranged husband has concocted a diabolical plot to make her look like a relapsing drug addict ... at least that's what Jodie's gut is telling her.

Jodie just called in to "TMZ Live," telling us she's got a hunch as to who started the false rumors about her entering rehab for substance abuse -- and strongly insinuated that her estranged husband Morty Coyle is the mastermind.

She said, "Breakups are hard and certain people [her husband] don't make them easier. People get weird and stalkerish ... You never really know someone until you break up with them."
