Mr. Big is adding a plus one to his little family!

Chris Noth has announced his wife is pregnant with their second child, and it's a boy!

Taking to social media to reveal the exciting news on Wednesday, the 64-year-old "Sex and the City" heartthrob showed off Tana Lynn Wilson's growing bump.

"Orion is getting a brother," he stated before joking, "I better get my ass in shape."

Fans are freaking out about the pregnancy, but one person in particular is really pumped for the star.

Sarah Jessica Parker!

Sarah Jessica Parker, aka Carrie Bradshaw, commented on Noth's post in the cutest and most supportive way possible, but made sure to sprinkle in a little sarcasm for her forever on-screen lover.

"Oh. My. G-d!!!!!!!!!! I'm so happy for you both!!!" SJP responded.

His former "Gone" co-star Leven Rambin made sure to send her kind words too.

"CONGRATULATIONS FAM!!" she wrote.

Big Brother!

This is the second child for Chris Noth and his wife.

The duo said "I do" in 2012 and have one child together.

Their son, Orion Christopher Noth, who's named after his dad, is 11 years old.

Mr. Big -- Swoon!

Chris Noth is an iconic face in Hollywood and made quite the name for himself.

He starred as SPJ's on-screen love, Mr. Big, in the "Sex and the City" TV show from 1998-2004, before his large role in all three franchise movies.

Before "Sex and the City," he got his TV start as Mike Logan on "Law & Order" and has continued to build his silver screen resume ever since.

Congrats!
