Dierks Bentley and his wife, Cassidy, got a wonderful Christmas gift in daughter No. 2.

"Say what u want about santa's physique, but no arguing his impeccable timing! evie wanted a little sis for Xmas & JORDAN just arrived!” Dierks tweeted about 4 a..m. Christmas morning.

It should be no surprise that there was some music playing in the delivery room.

Dierks’ second tweet: “she chose the banjo driven part of mumford & sons 'awake my soul' as her walk on music . . . could be a troublesome sign.”

Congrats!
