May 21 (UPI) -- Succession star Kieran Culkin is going to be a dad of two.
The 38-year-old actor is expecting his second child with his wife, Jazz Charton.
Charton shared the news Thursday on Instagram on her 34th birthday. She showed her baby bump in photos with Kinsey, her 20-month-old daughter with Culkin.
"34," Charton captioned the post, adding a cake and hatching chick emojis.
Actress Brenda Song, the partner of Culkin's brother, Macaulay Culkin, wished Charton a happy birthday in the comments.
"Happy birthday, Jazz!!! Miss you guys!" Song wrote.
Song and Macaulay Culkin welcomed their first child, a baby boy, in April. The couple named their son Dakota after Culkin's late sister, who died at age 29 in December 2008.
Culkin and Charton married in 2013. The couple welcomed Kinsey in September 2019.
"I've never been more in love and we've never felt more complete," Charton said on Instagram at the time.
Culkin plays Roman Roy on Succession, which was renewed in 2019 for a third season on HBO. The series co-stars Brian Cox, Alan Ruck, Jeremy Strong, Sarah Snook and Matthew Macfadyen.
