Zac Brown is awaiting the birth of his fourth child, a daughter. The Zac Brown Band frontman's wife Shelly is reportedly on bed rest as she is due some time next week.

Their first daughter, Justice, was born in 2007, daughter Lucy was born in 2008 and daughter Georgia was born in 2009, so Brown's been changing diapers more than he's been playing music lately, saying that the "diapers are flying. It's awesome," according to KWTX.

With three girls all under the age of four at home, the country star says he did still recently "knock dust off his guitar" and do a little playing. Brown is home now until he has to go out on tour in mid-March.

His next outing should be the Grammys on Feb. 13, as the Zac Brown Band are up for four: Best Country Performance by a Duo or Group With Vocals for 'Free,' Best Country Collaboration With Vocals for 'As She's Walking Away' with Alan Jackson, Best Country Song for 'Free' and Best Country Album for 'You Get What You Give.'

As was previously noted, the 'Chicken Fried' singer and his band found out this week that they're up for five ACM nominations, which include Top Vocal Group, Album of the Year for ‘You Get What You Give,' Single of the Year, Song of the Year and Vocal Event of the Year featuring Alan Jackson for ‘As She’s Walking Away.’
