Another precious little boy has entered the world. According to her personal website, Tori Spelling and husband Dean McDermott welcomed a son, the couple's fourth child together Thursday, and first shared the news on Twitter when she posted, "It's a boy!!!!"

"We are so excited to announce the birth of the newest member of the McDermott family," she wrote. "Please join us in welcoming Finn Davey McDermott."

Aw, Finn! (Anybody else having a "Gleek" moment right now?)

Giuliana and Bill welcomed a son, too!

Finn arrived at 5:39 p.m., weighing 6 pounds, 6 ounces and measuring 20 inches long.

Spelling and McDermott announced the pregnancy back in March. "Dean, Liam, Stella Hattie and I are beyond thrilled to announce that another little McDermott is on the way!" Tori posted on her website. "We feel truly blessed that another angel has found us."

Look at all these famous families!

The couple are already parents to Liam, 5, Stella, 4, and Hattie, 10 months. 

Congratulations to the growing family!
