Alec Baldwin and Hilaria Baldwin have officially welcomed the newest member of their big, happy family. 

The famous mama gave birth to the couple's fourth child together, a son, on Thursday, she announced on social media. 

"He's here! He's perfect! 8lbs 2oz #wegotthis2018," Hilaria captioned a sweet photo of mom, dad and baby together. The proud parents have not yet revealed the youngster's name. 

The little guy joins big sister Carmen, 4, and older brothers Rafael, 2, and Leonardo, 1.

With three births already under her belt, Hilaria has become a pro at pregnancy by this point. "I'm not saying I won't have another meltdown when this new baby is born! But with a fourth pregnancy, you see the light at the end of the tunnel earlier. There's calmness and comfort from experience," she previously told Parents ahead of the birth.

The celebrity mom and dad first revealed the news of their fourth little one on the way to fans—and their "Baldwinitos"—in November 2017. 

"Our Baldwinitos are getting a new teammate this spring," she announced on social media at the time. "I'm gonna make them a special cake to tell them if it's a boy or a girl...I'll post it tomorrow midday. We are so excited!"

The adorable family celebrated the youngster over cake with a surprise blue filling the next day. Six months later, he's finally here!

As the fam is welcoming their newest addition into the fold, Carmen has been particularly excited.
