Jason Aldean and Brittany Kerr have officially tied the knot!

The couple were married in an intimate evening ceremony on Saturday (March 21) in Mexico.

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

Aldean and his bride, a professional dancer and former American Idol contestant, celebrated with family and friends, including Aldean's two daughters from his previous marriage, Keeley and Kendyl.

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

This marriage is Kerr's first and Aldean's second; he was was previously married to Jessica Ussery for 12 years. Aldean and his first wife separated and divorced in 2013, following a huge scandal, when TMZ published photos of the the singer kissing Kerr at an L.A. night club in September 2012. Both Aldean and Kerr apologized for the incident, with Aldean attributing it to alcohol.

The newlyweds first confirmed that they were dating in March 2014; Aldean's reps said that the pair began their relationship after his split from Ussery. Aldean proposed to Kerr in September at the San Diego Zoo.

Aldean is scheduled to resume his 2015 Burn It Down Tour on March 26 in Toledo, Ohio.

Congratulations to the happy couple!
