Mario Lopez and wife Courtney Mazza are celebrating the arrival of their third bundle of joy, and the little guy already has some pretty famous friends.
The "EXTRA" host broke the news Monday morning, telling fans, "It’s a BOY!!!! Healthy, beautiful baby boy... Santino Rafael Lopez!"
He added that, "Baby & Mom are doing great," and specifically, "Mrs. Lopez came through like a Champ!"
Along with photos of little Santino, Daddy Lopez shared photos of himself in scrubs and his wife in her hospital bed ... looking beautiful, but tired.
It didn't take long for celebrities to start sending in their well wishes and congratulations for the arrival of the new baby.
Mark Wahlberg, who regularly trains with Lopez, wrote "Congrats!! That was quick," on his friend's IG feed.
"Stranger Things" star Millie Bobby Brown wrote, "Awww so beautiful congratulations," while actress Jordana Brewster wondered, "how does mrs Lopez look so stunning after giving birth?"
Some of Lopez's boxing buddies got in on the congratulations too, especially legendary trainer Freddie Roach, who wrote, "Big congratulations to you."
Back in January Lopez and his wife first broke the news via Instagram that the family was expecting a third child.
They previously had 8-year-old daughter, Gia, and 5-year-old son, Dominic.
Throughout her pregnancy, Courtney posted tons of cute videos showing off her growing baby bump.
She also didn't slow down on family activities, as the whole Lopez crew was recently seen at the "Toy Story 4" premiere in L.A.
Days before giving birth, Courtney was showing that she was ready to pop while on a Baby Moon vacation in Newport Beach, CA.
