The 65-year-old actor — best known for playing Mr. Big in the SATC franchise — and his actress wife Tara Wilson, 37, have named their new son after the English romantic poet John Keats. (Fans of the HBO show and its big-screen follow-ups will also remember Keats as one of the lovers referenced in Carrie Bradshaw’s book, Love Letters of Great Men.)

Noth announced on Instagram: “Down from the heavens comes our second son — Keats! ‘A thing of beauty is a joy forever.’”

Noth’s Sex and the City co-star Kristin Davis was quick to congratulate him, commenting: “Oh my goodness! He is so perfect and beautiful! Congratulations to you all.”

The couple’s first son Orion — named after the constellation — was born in January 2008.

Announcing Wilson’s second pregnancy in September 2019, Noth joked, “Orion is getting a brother — I better get my a** in shape.”

Noth and Wilson began dating almost 20 years ago when she was working as a bartender.

The couple broke up numerous times at the start of the relationship, much like Carrie and Big, before marrying in 2012.

“At the beginning, I’d say we broke up every two weeks,” Wilson told Canadian magazine Maclean’s in 2008. “Then it was every two months. Then it was every six months.”

Noth added: “We’d break up so often and I’d be like, ‘That’s it! It’s over!’ Then a few weeks later I’d be like, ‘Why am I missing her so much? Get over it god******!’ It got to be too much of a hassle to be apart.”
