Josh Kelley and his wife Katherine Heigl have welcomed their third child!

Joshua Bishop Kelley Jr. was born on Dec. 20, a rep for the couple tells People. He is the first boy and first biological child for singer Kelley and actress Heigl; their two daughters, Naleigh Moon, 8, and Adelaide Marie Hope, 4, were both adopted.

Kelley and Heigl shared the news of her pregnancy in June; at the time, they said that Joshua was due in January, and that their daughters "could not be more excited to welcome their new sibling into the fold.” The couple adopted Naleigh from South Korea in 2009, and Adelaide joined their family via domestic adoption in 2012.

In addition to his sisters, Kelley and Heigl's son will also have his cousin Ward — the son of Lady Antebellum singer Charles Kelley and his wife Cassie — to play with. Charles Kelley is Josh Kelley’s younger brother.

Josh Kelley released New Lane Road, his first new album in five years, in April of 2016. The project features the song “It’s Your Move,” the music video for which Heigl directed and co-stars in.
