Tori Spelling shared a baby bump photo on Sunday ahead of her son's impending birth.
"#bumpproud Can't wait to meet you little man... my little Pisces. #6weekstogo #littleman #number5," she captioned the picture.
Spelling and McDermott married in 2006, and are already parents to 9-year-old son Liam, 8-year-old daughter Stella, 5-year-old daughter Hattie and 4-year-old son Finn.
The couple announced the actress' pregnancy in October.
"It was a total surprise," Spelling told People at the time. "But we always wanted a big family. I'm really excited.""Dean was saying, 'We just got Finn out of diapers; I thought we were in the clear!'" she admitted. "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," the star qualified. "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."
She previously told E! News it's "nice" to experience a pregnancy while her kids are older.
"I had them all pretty quickly and all back to back, so they were little," the actress said. "Now they're four through nine, so they can enjoy this pregnancy and experience it with me. It's a whole difference experience."
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."
