It's a boy for actress Malin Akerman!

Rock of Ages star Malin Akerman, 34, is a brand new mom!

She and her hubby, musician Roberto Zincone, welcomed their first child — a boy! — yesterday (Tuesday, April 16).

"My husband and I welcomed our beautiful, healthy baby boy to this world this morning! Biggest joy of my life!!! #lovemykid," Malin tweeted.

Moments later, she tweeted the baby's name: "PS and his name is...Sebastian Zincone :))) Love him more than life itself!! #whatafeeling !!!"

Awww, Sebastian! So handsome.

Congrats to the family!

Off I go again to update our Who's Pregnant in Hollywood (and who just had a baby!) gallery. See you there!

Love!
