Mario Lopez, who you may know from hosting 'Extra' and 'The X Factor' -- or because he was A.C. Slater back in his 'Saved by the Bell' days -- has welcomed a second child, a boy named Dominic, with his wife, Courtney.

Mario announced the news late last night (Sept. 9) via Twitter, because why waste money on a representative when social media is free. They originally made the announcement of Courtney's pregnancy on 'Extra.'

The excited messages read:

Their new baby came in at 7 lbs., 2 oz., and according to a statement by 'Extra' (via Us Weekly), "Mother and baby are doing well."

In addition to Dominic Lopez, the couple also have a daughter, three-year-old Gia Francesca.
