"Dean, Liam, Stella, Hattie, and I are beyond thrilled to announce that another little McDermott is on the way! We feel truly blessed that another angel has found us."
Spelling -- who gave birth to the couple's third child, Hattie, just five months ago -- did not reveal any additional details about the pregnancy, including how far along she is.
In addition to Hattie, a baby girl born on October 10, Spelling and McDermott are also parents to 3-year-old Stella Doreen McDermott, who was born in June 2008, and 5-year-old Liam Aaron McDermott, who was born in March 2007.
Liam was born a week before the first-season premiere of Spelling and McDermott's Tori & Dean: Inn Love Oxygen reality series, and Spelling coincidentally gave birth to Stella a week before the third-season debut of Tori & Dean: Home Sweet Hollywood.
Tori & Dean: Home Sweet Hollywood viewers got their first peak at Hattie during the show's sixth-season premiere, which aired in November and included a special live peek into the family's home.
