Late on Sunday (July 10) night, Carrie Underwood and Mike Fisher shared their love story with the world.

First, Underwood posted a picture of her and her husband having a meal on their vacation in Mexico.

"Six years ago today, I said 'I do,' to this handsome fella," she wrote on social media. "I meant it then and I mean it now. God put us together and continues to bless our marriage. I couldn't imagine this life without you, @mfisher1212. I am thankful for these past six years together (and, of course, for our beautiful son, Isaiah) and I look forward to spending the rest of our lives in love."

Fisher was quick to follow, with his own picture of their wedding day in 2010.

"Six years ago today we were married," he wrote. "Time sure does fly when you're having fun and you marry up. I'm very grateful to have an amazing wife and mother by my side!!"

Underwood has been posting pictures for the past few days of their trip together, including some cliff-diving videos of Fisher, an obligatory duck face selfie, a picture of her vacation coffee and a shot of her in a high-neck bikini.

She also tweeted that the trip isn't the best for her usually healthy routines.
