Congratulations are in order for Tori Spelling and Dean McDermott.

The Beverly Hills, 90210 alum, 43, and the Chopped: Canada star, 49, are expecting their fifth child together, PEOPLE reports.

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

The couple are already parents to sons Liam, 9, and Finn, 4, and daughters Stella, 8, and Hattie, 5. Dean is also dad to 18-year-old son Jack from his previous marriage to celebrity chef Mary Jo Eustace.

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

“We need a Sprinter van!” says McDermott, adding that baby number five is definitely meant to be.

“This baby happened at the best time,” Spelling shares. “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.”

Congratulations to the Spelling-McDermott family!
