Chris Noth becomes a father of two

Chris Noth has become a dad for the second time at the age of 65.

The Sex and the City star announced the happy arrival in a post on his Instagram page on Tuesday, revealing he and wife Tara Wilson had welcomed a baby boy called Keats.

"Down from the heavens comes our second son- Keats! 'A thing of beauty is a joy forever'," Chris captioned the snap of Keats sucking on his fist while asleep on a pillow.

He quickly received messages of congratulations from his famous friends, including his former Sex and the City co-star Kristin Davis, who wrote: "Oh my goodness ! He is so perfect and beautiful ! Congratulations to you all."

Keats is the second son for Chris and Tara, who are already parents to 12-year-old Orion.

Chris famously played John James 'Mr. Big' Preston, the love interest of Sarah Jessica Parker's character Carrie Bradshaw, on the hit U.S. show.

The veteran actor and Tara, 37, began dating in 2002 and wed in 2012.
