Even if he doesn't get their votes, Dancing with the Stars
contestant Noah Galloway just won America's hearts.
Galloway, 33, proposed to Jamie Boyd during Monday's live show, presenting his Army Reserve specialist girlfriend with a two-carat, princess-cut diamond on an 18-karat white gold band from XIV Karats in Beverly Hills.
After his performance to David Cook's "Time of My Life" earned rave reviews, host Erin Andrews brought Boyd along for Galloway's backstage interview.
"You're amazing," Boyd said of her beau. "You're a beautiful dancer and you have a beautiful heart."
"The song, the 'Time of My Life,' you've given it to me," Galloway said, getting on bended knee as the crowd cheered. "I've got to do this here."
The Army veteran and double amputee had been planning to pop the question ever since Boyd secretly watched him samba before surprising him on stage

"Jamie has been so supportive throughout my entire journey. I have been wanting to propose for a while, and when she surprised me in the Skybox, it was such a shock, if I had the ring with me I would have done it right then and there," he tells PEOPLE. "That was a moment when I knew I wanted to propose to her on the show. I always thought if I made it to the finale I would propose, but I realized the competition is so stiff I couldn't let the opportunity pass me by in case this is the end of the road for me on the show."
