So here’s what we think happened: Tori Spelling heard about the birth of Johnny Knoxville’s daughter last week, so not to be outdone she kicked her pregnancy into overdrive. That’s how it works, right? In any event, Tori and her husband Dean McDermott welcomed a new member to their family yesterday morning! “Our family’s so happy 2 announce [that on] 10/10/11 baby girl Hattie Margaret McDermott was born at 7:08am! Xoxo,” the new mother tweeted. She also attached a squee-inducing photo of the little bundle’s feet. The couple announced that they were “expecting” back in April, but vowed not to learn the gender of the baby until the big day. In addition to the newborn, the reality show stars have a 3-year old daughter Stella and a 4-year-old son Liam, as well as Dean’s teenage son Jack from a previous marriage. Congrats to the new and enlarged family!
