The Spelling/McDermott family has a new addition!
Finn weighed 6 lbs., 6 oz. and was 20 inches long when he was born, Spelling wrote on her website.
"We are so excited to announce the birth of the newest member of the McDermott family!" Spelling wrote. "Please join us in welcoming Finn Davey McDermott."
The pregnancy was unplanned, with Spelling finding out she was expecting again just five months after giving birth to her daughter Hattie last October.
Finn joins siblings Liam, 5, Stella, 4, and Hattie, 10 months.
