Listen to Dierks Bentley on iHeartRadio

Country star Dierks Bentley and his wife Cassidy Black are making room for a new addition to the family. 

The couple welcomed their third child, a son they named Knox, on Wednesday night.  Dierks took to Twitter to announce the arrival of his baby boy, adding that he was about to have the best tasting cold beer of his life and that he was proud of his wife. 

Bentley also said he had "mad respect for doctors, nurses and everyone at hospitals" and thanked fans for their support. 

At home, little Knox joins big sisters Evelyn Day, who is four years old, and Jordan Catherine who is two.
