Over the summer, Dierks Bentley and his wife Cassidy announced that they were expecting a second child in December, but now they have more exciting details to share: It's a girl!

Bentley let the news slip to Gerry House during an interview at Nashville radio station WSIX. The new baby is due this month, and she'll be joining big sister Evie, who is two years old.

The new addition to the family will come just in time to help them celebrate Bentley's recent Grammy nominations. The singer is up for three awards, including Best Country Collaboration With Vocals for 'Bad Angel' (with Miranda Lambert and Jamey Johnson); Best Country Collaboration With Vocals for 'Pride' (with Del McCoury and the Punch Brothers) and Best Country Album for his fifth studio release, 'Up on the Ridge.'

Keep an eye out for updates on the baby's upcoming birth on Taste of Country, and tune in to CBS for the 53rd Annual Grammy Awards at 8PM ET on Feb. 13 to see how Bentley makes out.
