July 2005--Top recording trio Rascal Flatts may burn up the country music charts with romantic melodies such as "I Melt", but it looks as though the award-winning group will soon be playing another tune--The Wedding March.

On June 30, 2005 the band's guitarist Joe Don Rooney slipped an engagement ring on to the finger of Playboy's 2005 Playmate of The Year Tiffany Fallon, who CMT viewers will recognize as the leading lady in Toby Keith's tongue-in-cheek video, ''Who's Your Daddy?"

The prospective groom popped the question on a cruise ship drifting on the water off Cabo San Lucas, Mexico. The couple have not announced a wedding date.
