Tori Spelling and husband Dean McDermott have acknowledged money is currently really tight for their family.

"It's no mystery why I have money problems. I grew up rich beyond anyone's dreams. I never knew anything else. Even when I try to embrace a simpler lifestyle, I can't seem to let go of my expensive tastes," Spelling said in an excerpt from her new memoir Spelling It Like It Is, which hit shelves October 22, according to People.  

Spelling was born into wealth as the daughter of Aaron Spelling, a famous Hollywood producer. In her career, she's starred in Oxygen's Tori & Dean: Inn Love and Tori & Dean: Home Sweet Hollywood, designed a jewelry line, and also hosted Tori & Dean: sTORIbook Weddings for the network.

"And then there's my shopping problem. I've bought ridiculous amounts of stuff for the kids, clothing, toys, crafts. We've traveled... I can't afford to live like [I'm rich] anymore. Our circumstances have changed. They say admitting the problem is the first step," added Spelling.

Spelling and McDermott -- who reportedly wants a vasectomy, which costs anywhere from $350 to $1,000, but can't afford one -- have been trying to budget their money and change their excessive spending habits since they have five children in the family: Liam, 6, Stella, 5, Hattie, 2, Finn 14 months, and McDermott's son Jack, 15, from a previous marriage.

"I haven't bought a purse in three years and it's fine. I look back on that girl who shopped at Gucci in my 20s, and I can't even relate. I can't believe I thought it was important," Spelling told People in its November 4 issue.

It's been about one year since Tori & Dean: Home Sweet Hollywood was canceled by Oxygen due to low ratings, but the couple is apparently looking forward to their new show on HGTV, Tori & Dean: Cabin Fever, which will premiere in Spring 2014.

"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," Spelling explained.

"We're in the entertainment business and things change year to year... We're all about repurposing. It's a really good value to have."

Spelling, 40, and McDermott, 46, wed in 2006 and welcomed their first child together in March 2007.
