The country music singer proposed to "Bachelor" alum Lauren Bushnell on Sunday in the backyard of her family's Oregon home.

The couple first shared the news with People magazine , and the two later confirmed their engagement on Instagram.

"I can't stop smiling," Bushnell wrote in a post. "I feel so incredibly blessed that every misstep, mistake and heartache has led me to you. I couldn't be happier to call you mine, forever. The journey was well worth it. Thank you Christopher Eric Lane for softening my heart and making it whole. 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."

Lane, 34, told People he was confident he would get a "yes," but there were still plenty of nerves.

"I knew she wouldn't want some elaborate crazy proposal," Lane said. "So, I decided to keep it pretty casual. I asked her parents for different places in Portland I could potentially take her to, but after a lot of thought I decided doing it at the family cookout would be the most laid-back setting and that she'd appreciate the simplicity of me proposing to her in her parents' backyard."

So Lane decided to go with what he does best -- make music. He wrote Bushnell, 29, a song titled "Big, Big Plans."

"Right now we're back in her hometown / and I'm down on one knee," Lane sang as he turned his lyrics into real-life actions.

Bushnell finally realized what was happening after she began processing the words to the song.

"I lost it," she told People. "It was the happiest moment of my life!"
