Rascal Flatts guitarist Joe Don Rooney is expecting his third child with wife Tiffany Fallon.

The couple, who are also parents to Jagger Donovan, 5, and Raquel Blue, 3, announced the exciting news on March 31.

"We are so thrilled and feel so blessed to bring another little angel into our world," the couple told PEOPLE Magazine. "Jagger and Rocky are very excited too. They're going to make a great 'big brother-big sister duo' as the Rooney circus continues."

Rooney and Fallon, who has held such honors as Miss Georgia USA 2001 and 2005 Playmate of the Year, got married on April 23, 2006. Two years later, on May 31, 2008, they welcomed their first child, a son named Jagger Donovan Rooney. Their second child, daughter Raquel Blue, was born on Sept. 7, 2010.

As the couple prepares for their third child, Rooney is also preparing to embark on his Rascal Flatts Rewind Tour 2014, which kicks off on April 4 in Las Vegas and wraps up in Toronto on Sept. 20.

Following the birth of their daughter, Rooney told PEOPLE Magazine, "Raquel Blue is so beautiful and we feel so grateful to have this sweet little angel round out our family. We feel blessed and are ready for the sleepless nights ahead."
