Joe Don Rooney will soon have a trio of his very own! The country star -- one third of the hit group Rascal Flatts -- is expecting his third child with wife Tiffany Fallon, his rep confirms to Us Weekly.

"We are so thrilled and feel so blessed to bring another little angel into our world," the guitarist, 38, said in a statement. He and Fallon, the second runner-up to Miss USA 2001, have been married since April 2006 and have two other kids together, son Jagger Donovan, 5, and daughter Raquel Blue, 3.

"Jagger and Rocky are very excited, too," he added. "They're going to make a great 'big brother - big sister duo' as the Rooney circus continues."

The baby-to-be also has an early fan in Rooney's bandmate Jay DeMarcus, who tweeted his congratulations to the happy couple on Sunday, March 30. "Congrats to my brother @JoeDonRooney," he wrote. "I'm proud to be an uncle again!!! @Tiffallon, love you guys!!!"
