The country star tied the knot with former "American Idol" contestant Brittany Kerr on Saturday night in Mexico, ABC News has confirmed.

"This is the best day ever," Aldean told Us Weekly. "I've got my girl here, my friends, my family. It's the best day ever!"

Added Kerr: "Today has been the best day of my life. I feel like the luckiest woman to have been able to marry my best friend."
