Tori Spelling and Dean McDermott Welcome Baby Girl

Former 90210 star Tori Spelling announced via Twitter Tuesday that she and her husband Dean McDermott have welcomed a third child, a beautiful baby girl.

“Our family’s so happy 2 announce tht 10/10/11 R baby girl Hattie Margaret McDermott was born at 7:08am! Xoxo,” Spelling, 38, tweeted to her fans.

In addition to Hattie, Spelling and McDermott, who married back in 2006, are also the parents of a four-year-old son, Liam, and a three-year-old daughter, Stella.

McDermott, 44, also has a 13-year-old son, Jack, from a previous marriage.

Throughout her pregnancy, Tori and Dean purposely refrained from learning the sex of the baby, saying they wanted it to be a surprise on the birth day. Tori also often claimed that her third pregnancy was not as easy as her other two.

“People always think the first one was the hardest.” Tori told People magazine, “But I’m like, ‘No the first one was easy for me because I could lay around all day. I didn’t have two little ones to take care of.'”

The couple, who originally met on the set of a TV movie, plans to introduce their new baby on the premiere of the sixth season of their reality show, Tori & Dean: Home Sweet Hollywood.

It airs November 29th at 10pm ET on Oxygen.
