For the third consecutive year, LeAnn Rimes will host and perform at the annual Colgate Country Showdown. Filmed at Nashville's historic Ryman Auditorium, the final competition boasts five finalists chosen from more than 50,000 contestants, all vying for the grand prize of $100,000. Competitors all begin at the local level, with over 450 radio stations hosting local talent competitions.

Now in it's 27th year, past finalists and winners include Sara Evans, Martina McBride, Brad Paisley, Miranda Lambert, Montgomery Gentry, Garth Brooks, Billy Ray Cyrus and Tim McGraw. Rimes herself is also a talent show veteran, competing on 'Star Search' when she was just 8 years old.

The Colgate Country Showdown is being taped this Thursday. It will air on local networks in syndication in February and March. For more information, visit
