The country music star went public about his relationship with the former American Idol contestant at the CMT Awards in June 2014 and became engaged in September of the same year. Jason was previously married to his high school sweetheart, Jessica Ussery, for 11 years.

While Jason doesn't do as much songwriting these days, he acknowledged that his new marriage inspires his work in other ways.

"When you're happy and everything's going good obviously that's inspiration for a lot of things, and for me it's about what kind of songs I record now," Jason said.
