The former Beverly Hills, 90210 actress reveals she and her family have downsized and cut back on their expenses following the cancellation of their latest reality show, Tori & Dean: Home Sweet Hollywood, last year (12), although she insists they are hardly broke.
She explains, "We're in the entertainment business, and things change year to year. 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 claims living a less extravagant lifestyle has helped her teach their four young children all about the importance of "repurposing", telling People magazine, "It's a really good value to have."
The financial cutbacks have prompted MCDermott to temporarily postpone a vasectomy, which can cost anywhere from $350 (£230) to $4,000 (£2,670), to prevent the couple from any unplanned pregnancies in the future.
Spelling, who grew up in a sprawling Los Angeles mega-mansion with her Tv mogul dad Aaron Spelling and her mum Candy, admits the lack of a regular pay cheque has forced her to stop buying designer goods, but it's a luxury she is happy to live without: "I haven't bought a purse in three years, and that's fine. I look back at that girl who shopped at Gucci in my 20s and I can't even relate. I can't believe I thought it was important."
However, Spelling's future is already looking up - she recently signed on to star in Mystery Girls, a new crime-fighting comedy with her Beverly Hills, 90210 pal Jennie Garth.
She adds, "I work really hard and there are certain things I want to give my kids. Like a big kick-a** farm! We've had lows, but I set goals and I keep going. I always bank on myself."
