Remember Justin Guarini? He’s the curly-haired cutie that competed alongside Kelly Clarkson in the first, yes FIRST, season of "American Idol". And now he’s a papa!

The "AI" alum, 32, welcomed a son with wife Reina Capodici early Tuesday morning. The little guy, named William Neko Bell Guarini, weighed in at 7 lbs., 2 oz. and joins big sister Lola, 6, who is Capodici’s daughter from a previous relationship.

“Quite a polite fellow for waiting until late Monday, early Tuesday to make his entrance,” Guarini told PEOPLE, who just finished his role in "American Idiot" on Sunday evening.

“With a full head of curly brown hair, wide open and alert eyes he came charging into the world," the proud papa gushed. “Reina is doing wonderfully and should be given a medal for going 10 months and 1 week with child,” he added.

Ten months?! She deserves Olymipc gold!

“She performed beautifully and only had to push for 15-20 minutes before the babe arrived. We’re resting comfortably in the hospital and can’t wait to introduce him to his big sister (who was asleep for the whole experience) when visiting hours commence.”

Congrats to the family!
