Mireille Enos is a mom again!

The Killing star and her husband, actor Alan Ruck, welcomed their second child together, son Larkin Zouey, on Wednesday, July 23, in Los Angeles, their rep confirms to PEOPLE exclusively.

Arriving at 7:07 a.m., Larkin weighed in at 7 lbs., 3 oz.

“We are awestruck by the arrival of our little boy,” the couple say in a statement. “The whole thing is a miracle.”

The pair are already parents to 3½-year-old daughter Vesper Vivianne, who told PEOPLE in February that she was looking forward to being an older sister. “I’m excited to meet MY baby,” she said at the time.

Ruck, 58, who is best known for his roles in Ferris Bueller’s Day Off and Spin City, is also dad to daughter Emma and son Sam, from his previous marriage.

Enos, 38, can next be seen on the fourth season of The Killing, streaming on Netflix starting Aug. 1, and the YA tearjerker If I Stay, which hits theaters Aug. 22.
