LOS ANGELES (AP) _ Rascal Flatts got plenty of face time on two of the highest-rated TV shows last night. The group performed two of their hits on ``Dancing with the Stars,'' for the series' 100th episode. It was a special edition, bringing back many of the favorite contestants from earlier seasons. For the record, R-and-B singer Mario was the contestant voted off this week. Earlier in the evening, the guys in Rascal Flatts were in the audience for ``American Idol'' and were introduced by host Ryan Seacrest. Even though they're on competing networks, both shows originate from the same L.A. studio complex.
