Tori Spelling has revealed that she is pregnant with her fifth child with husband Dean McDermott.

Tori Spelling Pregnant, Ordered To American Express

Spelling confirmed her latest pregnancy to People magazine, explaining that the news caught her and McDermott off guard.

“It was a total surprise,” Spelling told People. “But we always wanted a big family. I’m really excited.”

Spelling and McDermott are already parents to Liam, 9, Stella, 8, Hattie, 5 and Finn, 4. With the new addition on the way, Spelling said they’re back to square one.

“Dean was saying, ‘We just got Finn out of diapers; I thought we were in the clear!’ ” said Spelling. “For the first time this year, they’re all in school. So it’s like, wow. We’re basically starting over.”

As for how the couple plans to transport their five-child brood around Los Angeles, Spelling admits that they might be due for an upgrade. “We need a Sprinter van!” she said.

While the pregnancy is good news for the couple, Spelling and McDermott are still burdened by debt. Spelling has recently been ordered to pay American Express nearly $40,000 in unpaid bills.
