Rascal Flatts guitarist Joe Don Rooney is settling in to a familiar rhythm! People is reporting that Rooney and his wife, Tiffany Fallon, are expecting their third baby this summer. The couple are already parents to 5-year-old son Jagger Donovan and 3-year-old daughter Raquel Blue. A new baby isn’t the only summer project on the horizon: the band’s latest album, Rewind, is scheduled to release on May 13th. Sounds like summer might have some “Powerful Stuff,” alright!
