Dierks Bentley is a dad again! The two-time CMT Music Awards winner revealed late Wednesday night that he and his wife Cassidy welcomed their third child -- their first baby boy!

"Well…our boy Knox is here! about to have the best tasting cold beer of my life! so proud of my wife. she rocked it. crazy stuff. #beerme," the 37-year-old country crooner tweeted on Oct. 9. He added: "Mad respect for doctors, nurses and everyone at hospitals. can't believe y'all do that day in and day out. hard work making miracles happen."

The "What Was I Thinkin" singer revealed back in April via Twitter that he and his wife of eight years were expecting a third little one. "So my wife and I will be changing our family defensive strategy come the fall. Switching from man-to-man to zone. #3!" he wrote. "Advice, Tim McGraw?"

Two months later, Bentley revealed the baby's gender via a video message in June while on tour with Miranda Lambert, Lee Brice and Thomas Rhett as part of the Locked and Re-Loaded Tour.

Dierks and Cassidy are already parents to daughters Evie, 4, and Jordan, 2.
