Rascal Flatts' Joe Don Rooney and his wife Tiffany Fallon are expecting a little brother or sister for their 21-month-old son Jagger Donovan. Joe Don says."We are so excited to bring another child into our lives. Our son Jagger has been the biggest blessing."

Tiffany broke the news to Joe Don by the pool at a Los Angeles hotel in January, the same place where he learned she was pregnant with Jagger. Joe Don tells People magazine, "I was like, 'Wow! We're going to have to stop coming to this hotel. We'll have 16 of these things before long!'" The couple plans to find out the sex of the baby soon. Tiffany thinks it's going to be another boy, but Joe Don is thinking Jagger will soon have a little sister. The baby is due this fall.
