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."

Jodie Sweetin is adamant ... she's NOT currently being treated in a rehab facility -- but tells TMZ she currently WORKS at one.

We spoke to the former "Full House" star ... who tells us reports that she's in treatment for substance abuse are "such bulls**t ... I am absolutely NOT in rehab."

Jodie -- who once battled with a meth addiction -- says she currently works as a clinical logistics coordinator at an L.A. rehab center, and her employer has allowed her to live in a studio apartment on the property while she deals with her divorce from husband #3 Morty Coyle.

"I work for the center and they have been really generous in helping me with a place to stay as Morty wanted me out by the end of the month," Sweetin says.

"The owners of the facility said I could stay here as I got things figured out."

Jodie also says she's decided not to pursue full custody of the couple's 2-year-old daughter Beatrix -- and wants joint custody instead -- because she wants the kid "to have both of her parents in her life."

Jodie and Morty were married in 2012.

Jodie Sweetin's 2-year-old daughter could become the unfortunate centerpiece in her divorce -- TMZ has learned, Sweetin's estranged husband is gearing up for a full-on custody battle with the former "Full House" star.

We broke the story ... Sweetin filed for legal separation from Morty Coyle last month, citing irreconcilable differences -- but the kicker ... Sweetin requested full custody of their daughter.

But Coyle's not going down without a fight -- he just filed a response to Sweetin's docs, asking the judge to award him joint custody.

He also wants to block the court from awarding Sweetin spousal support.

Coyle and Sweetin had barely been married a year when they split. They were married in March 2012. Sad.

Jodie Sweetin has filed for legal separation ... TMZ has learned, and a Toyota is on the line.

The "Full House" star filed legal docs in L.A. County, citing irreconcilable differences. She married Morty Coyle in March, 2012.

Jodie and Morty have a daughter, Beatrix, who is 2. Jodie wants full custody.

Jodie is also asking the judge to award her their 2000 Toyota Avalon. Jodie wants the judge to make her and Morty split their $200 Kohl's credit card balance.

It's Jodie's 3rd marriage.

Jodie has had her struggles. She's struggled with addiction -- in particular, meth, ecstasy and coke.

"Full House" star Dave Coulier is about to have a less than full wallet -- turns out dude owes some big bucks in back taxes.

According to the Detroit News, the 49-year-old comedian racked up a combined federal and state tax debt nearing $50,000.

Records show the IRS filed a $37,063 lien against him in March of last year -- then California followed with a $11,793 lien in May of this year.

The comic is known for his charitable fundraising -- but, as they say, charity needs to begin at home.

Outside Villa, Evangelical hottie Candace Cameron still played second fiddle to the Olsen twins and all anyone wanted Dave Coulier to do was drop his Ranger Joe voice. How rude!

Her eight and nine-year-old daughters must be, like, soooo jealous.
