Three country veterans and one country newcomer will square off in the Semi-Finals round of the ToC Hottest Country Star of 2013 competition. Fans will ultimately decide who had the best year. Carrie Underwood, Danielle Bradbery, Blake Shelton and Luke Bryan all topped their Round 2 competition to get here. 

Underwood outlasted a strong charge from Taylor Swift's fans over the weekend, while Bradbery had very little trouble knocking off Kellie Pickler's followers. Shelton made quick work of Jake Owen, while Bryan's win over Tim McGraw was never really in doubt. All four artists are looking for a ticket to the Finals, which will feature the top male and top female artists of the year.

You can vote for each matchup once every day until both polls close on Nov. 17, 2013 at 11:59PM ET. Consider album and sales singles, concert performances, television exposure and other achievements when deciding who to vote for. The finals will begin next Monday morning (Nov. 18) and last through Friday, Nov. 22.
