Rascal Flatts are set to continue their American Living Unstoppable Tour in 2010, with Darius Rucker once again serving as opening act for the trio.

The tour, visiting 23 cities, gets underway again on Jan. 15 and 16 at the Mohegan Sun Arena in Connecticut, and will wrap up March 13 in Oklahoma City. On the first leg of the tour, which kicked off in June, the group sold 550,000 tickets for 39 shows, including two sold-out stadium shows at Chicago's Wrigley Field and Columbus' Crew Stadium.

This year alone, Rascal Flatts' tours have sold over one million tickets, bringing their four-year total to just over four million tickets sold.
