"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 couple’s bundle of joy came into the world at 5:39 pm weighing 6 pounds, 6 ounces and measuring 20 inches long.
The “90210” star shared the pregnancy news back in March on her blog. "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."
