Demi Lovato may be dating Wilmer Valderrama, but she is “engaged” to a five year old fan named Grant Burt, who was celebrating his birthday.

"Grant just turned 5, so we took him to see his (and our) favorite artist, Demi Lovato … yet again!" Grant’s mother Cassidy wrote on the YouTube video. "She pulled him up on stage and he proposed to her! They are now happily ‘engaged’ & we are thrilled!"

While onstage during her concert in Moline, Il., Lovato spotted a sign in the crowd being held up by a tiny fan saying, “Demi, I have a ring for you.” Lovato actually stopped the song to talk to him.

"Well, you are the cutest little boy ever,” she said, asking her little fan up to the stage. “I think since you’re up here we should make it official. You have to get down on one knee, and ask me, ‘Will you marry me?’”

The Grant family quickly passed the little plastic ring up to the stage, while Grant, knowing an opportunity when he sees it, quickly got down on a knee and proposed. Lovato happily accepted. Grant made the first move, getting a hug and a kiss from the singer. Lovato excitedly shared the picture on her Instagram account saying, “Oh and by the way guys…. I'M ENGAGED!!!!!!! Thank you to my future husband Grant… CUTESTEVER.”
