Rascal Flatts guitarist Joe Don Rooney and his wife, model Tiffany Fallon, are the proud parents of a baby girl. The couple welcomed Raquel Blue on Tuesday, September 7, at 4:26 PM CT. Both mom and baby, who weighed in at seven pounds, are said to be happy and healthy.

Raquel Blue is the couple's second child. Big brother Jagger Donovan Rooney was born in May of 2008.

"Tiffany and I are so excited to have brought a brand new baby into the world," Joe Don reports. "Raquel Blue is so beautiful and we feel so grateful to have this sweet little angel round out our family. Jagger is already an excited big brother; yesterday he gave her kisses and tried to feed her cookies! We feel blessed and are ready for the sleepless nights ahead."

Raquel is the fourth little Rascal, with a fifth coming right on her heels. Lead singer Gary LeVox has two daughters, while Flatts bassist/piano player Jay DeMarcus and his wife, Allison, will welcome their first child -- also a little girl -- in January.
