Just a few weeks ago, we reported that Dierks Bentley and his wife Cassidy were expecting a girl, and now the couple are happy to announce her birth. Baby Jordan arrived on Christmas morning.

"Say what you want about Santa's physique, but no arguing his impeccable timing! Evie wanted a little sis for Xmas, and Jordan just arrived!" Bentley tweeted early on Saturday, Dec. 25.

Jordan joins 2-year-old Evie, who must be thrilled to have a new baby sister for the holidays. And, according to Bentley's follow-up post on Twitter, it sounds like Jordan's got an ear for good music already.

"She chose the banjo-driven part of Mumford and Sons' 'Awake My Soul' as her walk on music," Bentley said. "Could be a troublesome sign."

The year of 2010 has been an exciting one for Bentley, who released the album 'Up on the Ridge' and is nominated for three Grammys: Best Country Collaboration With Vocals (for two different songs) and Best Country Album. The 53rd Annual Grammy Awards will air on CBS at 8PM ET on Feb. 13.
