Alisan Porter, best known for her role in the hit ’90s flick “Curly Sue,” welcomed her first child with husband Brian Autenrieth.

Porter gave birth to a little boy on Tuesday in Los Angeles. He weighed in at 7 lbs and measured 20 inches long.

The baby’s name?  Mason Blaise Autenrieth.

“We are all very in love,” the proud mom tweeted, along with a photo of her husband’s daughter Cassie holding the newest member of the family.

Porter, 31, and Autenrieth, 34, tied the knot back in March at Diablo Dormido, a historic California ranch in the Santa Monica mountains.

“We’ve been friends for 13 years and it’s the most incredible feeling to know you’re marrying your best friend,” the singer-songwriter and actress told PEOPLE at the time.
