Tori Spelling's cash-strapped husband Dean McDermott is reported to be some $45,000 behind in unpaid child support and alimony payments to ex-wife Mary Jo Eustace.

"Dean hasn't paid a dime since February," a source told Radar Online, adding of McDermott's 16-year-old son, "Dean owes it to Jack."

Meanwhile, rumors are McDermott claims he's "flat broke," and several media outlets have recently reported he and Spelling are now living "paycheck to paycheck" with their four young children.

Earlier this summer, the family held a garage sale as a way of raising cash, and not long after, they moved to a smaller home for the third time in just two years.

The last several years have been difficult for the family, with McDermott admitting in 2013 that he had cheated on his wife with a younger woman from his native Canada. Soon after that, he checked into a rehab facility known for treating patients for both and drug and alcohol addictions.

Spelling and McDermott first became a couple in 2005, when he abruptly ditched his then wife Eustace to take up with the former "90210 Beverly Hills" star.

Later, the two turned their own infidelity issues into a "True Tori" reality show, in which McDermott worked to earn back the trust of his wife, and the two worked on putting their marriage back together before a Lifetime TV audience.

Since then, the 48-year-old McDermott has vowed he's done having his personal issues play out on camera.

"Sorting out your problems in the town square is not the way to go about it," he recently told reporters.

The 42-year-old Spelling is the daughter of legendary TV producer Aaron Spelling. Before he died, he worked on such shows as "The Love Boat," "Charlie's Angels," "Dynasty," "The Rookies" "Charmed" and "7th Heaven."
