"I am so excited dude, I'm fired up! I'm like a little kid waiting for Christmas!" he tells Seacrest.

Lopez — who won't find out the baby's sex beforehand — says his family has been impatient for him to become a father.

"This is really late for me. In Mexican years I should have three to four kids right now!" he jokes. "My family was like 'About time!' when I told them!"
