Looks like Dierks Bentley and his wife Cassidy will be breaking out the blue paint because they've just announced they're expecting a boy!

At the Last Call Ball fan club party, Dierks broke the news that his third child will be a boy, saying he wanted his fans to be the very first to know.

Dierks' baby boy will join five year old sister Evalyn Day and two year-old sister Jordan Catherine sometime this fall.
