LOS ANGELES, Oct. 5 (UPI) -- Mom-of-four Tori Spelling is expecting a new addition to her family.
"It was a total surprise," she admitted in the interview. "But we always wanted a big family. I'm really excited."
Spelling and McDermott, who married in 2006, are already parents to 9-year-old Liam, 8-year-old Stella, 4-year-old Hattie and 4-year-old Finn. The actor is also dad to 17-year-old Jack with his ex-wife, Mary Jo Eustace.
"Dean was saying, 'We just got Finn out of diapers; I thought we were in the clear!'" Spelling said. "For the first time this year, they're all in school. So it's like, wow. We're basically starting over."
"This baby happened at the best time," she added. "Nothing is ever perfect, but I'm so madly in love with my husband and with our kids. The idea of adding to that is such a blessing."
The pregnancy news follows word that Spelling was ordered to pay $38,000 in credit card debt to American Express. The star's mom, Candy Spelling, had claimed in January that she was helping the family financially.
"I'm not paying extras like [the debt]," she said at the time. "I'm not paying any back payments. Just for the house and the kids' school and the food. I don't know [why she missed payments]. Extravagance, I guess."
Spelling is known for playing Donna Martin on Beverly Hills, 90210, and has since appeared in a number of TV movies. She and McDermott also starred on the Lifetime reality series True Tori.
