Mario Lopez Live Tweets Birth of Son ― Then Goes Out to Celebrate

News flash: Mario Lopez has welcomed a baby boy.

The "Extra" and "X Factor" host had a late night on Monday as his wife, Courtney Mazza, delivered their son, Dominic Lopez, in Los Angeles. And the 39-year-old gave his followers the play-by-play of his thrilling evening.

The excitement started at about 9 p.m. when the "Saved by the Bell" alum posted, "Whoa... Cutting it close. Just wrapped @TheXFactorUSA & I'm rushing to the hospital. Baby Lopez #2 is coming tonight! Baby better wait for me."

He then shared photo of a very calm looking Mazza ― with whom he has a daughter, Gia, who will be 3 this week ― all scrubbed in and ready in the delivery room.

"It's game time," he wrote. "Waiting for the Dr... @CourtneyMLopez & I are ready to go! Is it a boy or a girl???"

While waiting things out, Lopez distracted himself with football (the San Diego Chargers disappointed him), but at just after 11:30 his son was born.

"It's a boy!!!!!!!!!!!!!!" he tweeted. Please welcome Dominic Lopez to the world! Couldn't be happier... @CourtneyMLopez & baby are doing just fine... :)"

Just reading his tweets of anticipation exhausted us, but not Lopez. By 1 a.m. he was out celebrating. "I am in heaven right now.... And in a bar," the new dad shared in his final tweet of the night, tagging it #CelebratingDominicLopez.

The baby, who has curly black hair and a dimple like dad, is named after Mazza’s late grandfather. He will go by the nickname Nico.

We're not sure what time Lopez's head finally hit the pillow, but we're certain he must have slept well. What a day!
