"It's a boy!!!!!!!!!!!!!! Please welcome Dominic Lopez to the world," Lopez tweeted. "Couldn't be happier… Courtney and baby are doing just fine." Aww, so cute! I like that they went with a name that's not too traditional, but also not completely out of the box.

Earlier in the day, Lopez, who didn't know the baby's sex beforehand, revealed the anticipation was "killing" him. He also shared an adorable photo of him kissing his wife's cheek, dressed in hospital gear while waiting in the delivery room. "Waiting for the Dr," he wrote alongside the snapshot. "@CourtneyMLopez and I are ready to go! Is it a boy or a girl? #BabyLopez."

Making the happy occasion even better?  Dominic was actually born just two days before the birthday of big sister, Gia Francesa, who is set to turn three on Wednesday. Looks like the second week of September will be a busy and fun-filled one for the Lopez family every year!

I'm so thrilled for these two! They are such a great couple and have been really dedicated and loving parents to little Gia. I know they'll be equally as devoted to their little guy. Congrats to them and all of their loved ones!
