"Thank you Christopher Eric Lane for softening my heart and making it whole," she continued. "Never going to stop telling you how much I love you and I will hold onto you forever and ever! Lauren Lane has a nice ring to it."
This relationship update comes about seven months after the couple took their romance public, making their red carpet debut in November at the 66th Annual BMI Country Awards in Nashville, followed by an appearance at the 2018 Country Music Awards.
"She's the first date that I've ever brought to any award show," Chris told E! News at the time. "She's an amazing girl, no doubt about it."
In March, the couple officially moved in together in Nashville. The following month, while on the red carpet at the 2019 ACM Awards, Chris told E! News there's "no doubt" he's going to marry Lauren.
