Tori Spelling has a New Baby Daughter!

Tori Spelling and Dean McDermott welcomed their third child together on Monday – a little girl!

“Our family’s so happy 2 announce [that on] 10/10/11 [our] baby girl Hattie Margaret McDermott was born at 7:08am! Xoxo,” tweeted Spelling, along with a photo of her daughter’s feet.

The 38-year-old actress and her husband decided early in the pregnancy that they wanted the sex of the baby to be a surprise.

“We’ve been blessed with a boy and girl already, so this time we’ve decided to do it the traditional way and not find out the sex,” Spelling told PEOPLE in April.

Baby Hattie joins the couple’s two other children – Stella, 3, and Liam, 4. McDermott also has a 13-year-old son from a previous marriage. 

Congratulations!
