Third time is an extra-special charm! Congratulations are in order for country star Dierks Bentley and his wife, Cassidy, as they have welcomed a third addition to their family — a newborn son named Knox!

"Well… our boy Knox is here!" Dierks tweeted late last night, October 9. "About to have the best-tasting cold beer of my life! So proud of my wife. She rocked it. Crazy stuff. #beerme."

The two-time CMT Music Awards winner also tweeted his thanks to those who help women like Cassidy usher their new bundles of joy into the world: "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."

It's the first son for Dierks and Cassidy — Knox joins older sisters Jordan, 2, and Evie, 4. In fact, the only other boys in the household are their two pooches: Jake and George.

The proud mom and pop have been married for nearly eight years, having tied to knot in Mexico in December 2005.

Now that they've gone through the rigors of childbirth, we're betting the happy parents are ready to heed the title of one of his hit songs and "Settle for a Slowdown."

Congrats, you two!
