“I didn't say yes…I said HELL YESSSS!! Last night, the best man I've ever met got down on one knee in my little pink childhood home..in the same room I played with my ponies and barbies and asked me the easiest question I've ever been asked,” the bride-to-be sweetly wrote. “I finally know what everyone means when they say ‘you just know.’”

In a separate post, the 28-year-old revealed how her fiancé proposed. “We had just been at my parent's house randomly having a night of watching bittersweet old home tapes of all these beautiful family memories that were made in this little, old country house I grew up in that I now have,” she explained.

“We came back to that house afterwards and he had somehow pulled off having my sister + brother in-law sneak off and completely decorate my childhood bedroom in the most nostalgic and perfect Christmas decorations.”

She continued, “I was bewildered and confused when I saw it all and turned around… and he was on his knee with a baby pink velvet ring box and the sparkliest thing I've ever seen!”

“Then my sister busted in and captured it all with her camera. It was so beyond special. Of all the places in the world I've gotten to see, nowhere could mean more than this happening in tiny Golden, Texas in the house that completely made me who I am,” she adorably added.

It’s been a helluva year for the brunette beauty, who nabbed a Grammy nomination for Best Country Album in February.
