Jesse Williams is on call for daddy duty — again!

The Grey’s Anatomy star has welcomed his second child with wife Aryn Drake-Lee, a source confirms to PEOPLE.

Williams, 34, and the real estate broker — who are already parents to 22-month-old daughter Sadie — have reportedly welcomed a son.

After welcoming their first child in 2014, the actor — who stars as Dr. Jackson Avery on the hit series — told PEOPLE he was balancing his baby bliss with sleep deprivation.

“It’s hard to describe. It’s wonderful — a new discovery every day. It’s great and I’m loving it,” he said of fatherhood.

“Not getting too much sleep … I’m just trying to put together three solid hours of cogent communication!”
