Tori Spelling has apparently run into some money problems.

According to legal documents obtained by ET, the 42-year-old actress has a balance of $37,981.97 on her American Express card, and is now being sued by the credit card company for payment. According to the papers, Tori hasn't made a payment since June 26, 2015 -- and the payment in question, for $1,070 -- was returned.

"No part of said sum has been paid, although demand for payment has been made," the documents read about Tori's credit card balance.

American Express is now asking for full payment of the remaining balance, which will also include interest.

Tori's mother, 70-year-old Candy Spelling, claimed she's already been paying her daughter's bills in an interview with TMZ posted on Wednesday.

"I've been helping her out, I've been paying all her bills now, except I'm not paying extras like that," Candy said in response to Tori's lawsuit news. "I'm not paying any back payments -- just for the house, and the kids' schools, and their food."

When asked why her daughter has allegedly missed payments, she replied, "I don't know. Extravagance, I guess."

ET has reached out to both Tori and Candy for comment.

Tori has been open about her financial struggles in the past. In October 2013, she told People that her husband, Dean McDermott, decided against getting the vasectomy he wanted [which ranges from $350 to $1,000, according to Planned Parenthood] after their business manager said the couple couldn't afford it.

"We're in the entertainment business, and things change year to year," she explained at the time. "We don't have a series on the air right now, so we have to be more restrictive of what we can spend, just like anyone who doesn't currently have a steady job."

In her 2013 memoir, "Spelling It Like It Is," the mother-of-four also admitted she has a "little shopping problem."

"It's no mystery why I have money problems," she wrote. "I grew up rich beyond anyone's dreams. Even when I try to embrace a simpler lifestyle, I can't seem to let go of my expensive tastes ... And then there's my little shopping problem ... I can't afford to live like this anymore. Our circumstances have changed. They say admitting the problem is the first step."

Although at least Tori's marriage appears to be better than ever these days. ET caught up with the couple at David Tutera's 50th Birthday Party in Los Angeles this past Friday, where Dean couldn't stop gushing about his wife. The two are celebrating their 10-year wedding anniversary in May.

"She's amazing. She's stunningly hot!" Dean said. "I'm the luckiest guy in the world. I have a super-hot wife."

Tori also told ET that following past infidelity and marriage woes, the couple has had a "great, amazing rebirth of [their] relationship."

"Our relationship is in the best place it's ever been," Dean added.
