It's a boy!

Supermodel and actress Devon Aoki and her fiance James Bailey are the proud parents of a baby boy, Bailey confirmed via Twitter.

Tweeting a pic of the newborn Friday, Bailey later gushed about his and Aoki's new arrival. "Celebrating the birth of our son and Devon and my anniversary yesterday is more than I could ever ask for. Our family keeps growing," he blogged.

It is the first child for the 28-year-old Aoki, who began modeling at the age of 13. Having appeared in films such as 2 Fast 2 Furious and Sin City, Aoki is the daughter of former Olympic wrestler Hiroaki Aoki, who later founded the Benihana restaurant chain (he passed away in 2008).

Aoki and Bailey got engaged last summer.
