Thomas Rhett And Lauren Akins are still going strong after 12 years of marriage and four children!

On Monday, Oct. 28, the country superstar, 34, shared a sweet throwback photo and a current image side-by-side featuring himself and his wife, also 34, just a few years apart.

In the first shot, the couple can be seen as high school students posing for the camera holding bags of flour, presumably while taking a lesson on how to take care of a baby. In the second photo, the couple poses in nature with their four children as they go hiking, all smiling.

“2 bags of flour turned into 4 real ones very quickly…”, captioned the musician, tagging his wife and adding the hashtag: “#whatcouldgoright”.

Rhett and Akins have been candid about their long relationship, which began way back in elementary school, when they first met. They then got together as adults and after six months of dating, the couple got engaged and married in October 2012, when they were each 22 years old.
