Tori Spelling and Dean McDermott welcome their fourth child, baby boy Finn Davey

Tori Spelling has welcomed baby boy Finn Davey, her fourth child with husband Dean McDermott.

Tori Spelling, 39, gave birth on Thursday evening to 6lb, 6oz Finn Davey.

The star announced the happy news on her website, writing: “Please join us in welcoming Finn Davey McDermott.”

The post was followed by a tweet on the star’s verified Twitter account, linking to a photo of a tiny hand clinging to her finger.

“It’s a boy!” she wrote.

Tori Spelling confirmed she was expecting back in March – five months after the couple welcomed a daughter.

She posted a message on the micro-blog, writing: “Our family has some exciting and life changing news to share,” with a link to her website.

“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,” she wrote.

Tori Spelling also posted a picture of her bump with her children’s hands resting on top of it.

In addition to 10-month-old Hattie, Dean McDermott and Tori Spelling, who married in 2006, are parents to five-year-old Liam and Stella, four.

Tori Spelling is also stepmother to Dean McDermott’s teenage son Jack, from a previous marriage.

The couple was out as late as Tuesday, with the mother-of-four showing off her blossoming bump on the red carpet for a kids’ event in Los Angeles.

Tori Spelling has previously insisted this pregnancy would be her last but admitted she was “sad” that she’ll never be expecting a child again.

She said: “I couldn’t be happier that I’m finally at the end and I get to meet the baby so soon, but I actually love being pregnant, so if it is my last, I’ll be sad never to be pregnant again.

“It’ll have been a precious moment in time and it’ll be over with, so it is sad.”

She also revealed her kids are looking forward to a time when she is not pregnant so that they can have pillow fights with her.

Tori Spelling said: “I got pregnant so quickly after I had Hattie that I think they’re just like, <<Oh, Mom’s constantly in a state of pregnancy>>.

“They say they’re going to be excited when I’m not pregnant anymore so I can have pillow fights again with them. That’s their big thing.”
