It's official: Jason Aldean is off the market!

The country singer and his 26-year-old fiancee Brittany Kerr confirmed to Us Weekly that they got hitched in Mexico on Saturday, March 21.

"This is the best day ever -- I've got my girl here, my friends, my family -- it's the best day ever!" Aldean said in a statement. He RT'd the Us Weekly announcement from his official Twitter account.

The two got engaged in September 2014 after two years of dating. Kerr is a former "American Idol" contestant. Aldean is a country star with five platinum albums and a slew of hit songs on the Hot Country charts.

Their relationship had a bit of a rocky start: They were photographed getting close and personal at a bar in Hollywood in 2012 -- while Aldean was still married to his first wife, high school sweetheart Jessica Ussery. They filed for divorce in April 2013, and Aldean and Kerr announced they were officially dating in March 2014.
