The baby weighed in at 7 lbs., 2 oz., according to the report, and joins big sister Lola, 6, from Capodici's prior relationship.

"Quite a polite fellow for waiting until late Monday, early Tuesday to make his entrance," Guarini told People. "With a full head of curly brown hair, wide open and alert eyes he came charging into the world."

"Reina is doing wonderfully and should be given a medal for going 10 months and 1 week with child," he added. "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."

Guarini, 32, wrapped up his run in the Broadway musical "American Idiot" on Sunday.
