The Craft Wars host and her husband, Dean McDermott, welcomed their fourth baby, Finn Davey McDermott, on Thursday evening, Spelling confirmed on her website.
"Please join us in welcoming Finn Davey McDermott," Spelling wrote of her 6 pound, 6 ounces bundle of joy.
The McDermott family's new arrival joins older siblings Liam, 5, Stella, 4, and Hattie, 10 months. (McDermott also has a teenage son, Jack, from a previous marriage.)
Confirming her pregnancy in March -- just five months after welcoming daughter Hattie -- Spelling, 39, caught flack for expanding her brood so quickly. And while the actress joked that it was her husband's insatiable sex drive that led to her unplanned pregnancy, McDermott said he doesn't regret ignoring doctor's orders to wait at least six weeks before getting intimate.
"It's so funny how everyone blames the man," McDermott, 45, told Celebuzz after Spelling confirmed their family was growing. "It's like, 'Oh my God, will you leave your wife alone?' But it takes two to tango. She wasn't putting up that much of a fight. But I have big shoulders. I'll take it."
