And baby makes ... seven!

Tori Spelling welcomed her fifth child, a boy, with husband Dean McDermott on Thursday, making them an adorable family of seven.

The former "Beverly Hills, 90210" star posted a sweet photo of her little one grabbing onto one of Dean's fingers on Twitter.

"We are so excited to announce the birth of the newest member of the McDermott family!" she captioned the snap. She then revealed the little tyke's name: "Please join us in welcoming Beau Dean McDermott."

The family said he weighed in at 5 lbs., 12 oz and measured 18½ inches in length.

Candy Spelling, Tori's mom, began spoiling her grandchild even before he came out of the womb with a lavish baby shower last month. More than 50 guests filled the swanky Bel Air hotel's main restaurant for a $40,000 luncheon planned by Mindy Weiss, the party planner to the stars.

The beautiful venue was decorated with hundreds of blue balloons, stunning floral arrangements and even a train set that ran from table to table!
