Joe Don Rooney of Rascal Flatts welcomed a new addition to his family with wife Tiffany Fallon in Nashville on Monday (Sept. 29). This is the third child for the happy couple.

People reports that Devon Olivia was born at 7:01PM weighing 6 lbs., 11 oz. Devon is a little sister to 4-year-old Raquel Blue and 6-year-old Jagger Donovan, and the whole family is very excited!

“We are so thrilled to finally become a party of five,” the parents gush. “Jagger and Raquel are so happy to be her big brother and big sister.”

Before the baby's arrival, Rooney joked about his busy schedule and how he only had a limited amount of days for Devon to make her arrival. Unfortunately, her birth didn't fall into that window of time off, but we're sure the country star didn't mind.

Of course, the newest little rascal is sure to be a looker, just like her mother and father. Fallon was a runner-up to Miss USA in 2001. She and Rooney and have been married since 2006.

Devon makes seven Rascal Flatts' kids in total -- Gary LeVox has two daughters, while Jay DeMarcus has both a daughter and a son.

Outside of his band and baby news, Rooney has been pretty busy, as he and Jagger were the inspiration for preppy golf fashion line. We bet Devon will be just as stylish!
