Tori Spelling Welcomes Son Finn Davey

Tori Spelling has a new man in her life – her newborn son.

The Craft Wars host, 39, announced the arrival of her fourth child with husband Dean McDermott on her website, writing, “We are so excited to announce the birth of the newest member of the McDermott family!”

Finn Davey McDermott was born Thursday, Aug. 30 at 5:39 p.m. He weighed in at 6 lbs., 6 oz., and is 20 inches long. Baby’s middle name, the same as his mother’s, honors Spelling’s paternal grandfather.

Spelling and McDermott, 45, already have three children together — Liam Aaron, 5, Stella Doreen, 4, and Hattie Margaret, 10 months. McDermott is also father to son Jack, 13, from a prior marriage.

The actress announced her pregnancy just five months after delivering Hattie.

“I was shocked, obviously,” she told PEOPLE of getting pregnant so soon after her daughter’s arrival.

But Spelling, who chose a delivery surprise for the second time, was also pleased to expand her family even more. “We feel truly blessed that another little angel has found us,” she said.
