NASHVILLE -- Sorry, ladies, there are no more bachelors in Rascal Flatts. Guitarist Joe Don Rooney tied the knot with Playboy's 2005 Playmate of the Year Tiffany Fallon on Sunday, in Mexico. All three members of Rascal Flatts -- Rooney, Jay DeMarcus and Gary LeVox -- performed songs during the post-wedding evening celebrations. Rascal Flatts goes back to touring on May 26, when their "Me And My Gang" tour relaunches in Holmdel, N.J.
