Tori Spelling Welcomes Baby Girl!

Tori Spelling and Dean McDermott added a brand-new baby girl to their family this Monday!

Tori announced the birth by tweeting: "Our family’s so happy 2 announce tht 10/10/11 R baby girl Hattie Margaret McDermott was born at 7:08 am! Xoxo,” and posting a photo of little Hattie's newborn feet.

The arrival of their second daughter was a double surprise for the couple. Tori and Dean had opted not to find out the gender of their third baby before it was born, telling Life & Style: "We thought it would be the ultimate surprise. How many times can you get a surprise like this?"

Well, baby Hattie decided to surprise her parents even more, coming a week early! "The baby wasn't due until next week, but it was an early present!" said an insider.

Obviously Tori doesn't feel it did her any harm growing up in the public eye, because Hattie will soon be joining her siblings Liam (4) and Stella (3) in the spotlight on the family's reality show. The new season of "Tori & Dean: Home Sweet Hollywood," airs on Oxygen starting November 29.
