Ali Larter [1] and her husband, Hayes MacArthur, became parents for the second time last week, welcoming a baby girl [2] into the world. The actress announced the exciting development on her website, writing, "It's a girl! We couldn't be more excited to share news of the arrival of Vivienne Margaret MacArthur on Thursday January 15th 2015. She came bearing gifts for her brother [Theodore Hayes MacArthur]: Batman sheets and lots of Gummy Bears!!! 7.5 lbs of love." The post included an adorable picture [3] of Ali and Hayes's bundle of joy, showing Vivienne looking peaceful while bundled up in a blanket.

News of the pregnancy first emerged in August, when Ali showed off her growing baby bump [4] during a joyful appearance on The Tonight Show Starring Jimmy Fallon. "I've been trying to hide as much as I can, and when you're in the public eye, it's really scary in the beginning," she said at the time. Congratulations, Ali and Hayes!
