Alisan Porter, known for the 1991 Curly Sue film, and husband Brian Autenrieth welcomed a son into their family. Baby boy arrived on Tuesday, July 17th, at 5:20 p.m. in Los Angeles. He weighed 7 lbs./3175 grams and was 20 inches/50,8 cm long. The newlyweds named him Mason Blaise.

Alisan, 31, tweeted, "Mason Blaise Autenreith. 7 lbs 20 inches long. Born 7/17 we are all very in love," and added a photo of Mason and his big sister Cassie, Brian's daughter from a previous relationship. The singer-songwriter and actress celebrated her baby shower last month, "It was a perfect day. I couldn't have imagined anything more beautiful. There was so much love."
