Demi, you're one sound friend.
Her fans were brought to tears on Friday night at her gig at The Forum in Inglewood, California on Friday night.
She invited American Idol's Rayvon Owen on stage. Totally clueless as to what was going on, Rayvon was then joined on stage by his partner Shane Bitney Crone, who surprised him by entering the stage via a secret stage door, as you do.
Shane then got down on one knee, and proposed to Rayvon.
*Cue the tears*
