There's another girl in the family for Tori Spelling!

The former "90210" star, 38, and husband Dean McDermott, 44, welcomed their third child together yesterday.

Tori just tweeted "Our family's so happy 2 announce tht 10/10/11 R baby girl Hattie Margaret McDermott was born at 7:08am! Xoxo" and posted the photo below:

The two already have son Liam, 4, and daughter Stella, 3. Dean also has a son, Jack, with his ex-wife.

Tori has been out and about throughout her pregnancy -- hitting a ton of red carpets with her growing belly. Check out her baby bump style in the gallery above.

Congratulations to the happy couple!
