Nu-metal pioneers Disturbed are currently on tour celebrating the 25th anniversary of their album The Sickness, and at last night's show in Sacramento, CA, frontman David Draiman proposed to his girlfriend Sarah Uli on stage.

She's apparently "down with the sickness" too, because she said yes. This all went down before the second-to-last song of their set, because everyone knows you go to a Disturbed concert to witness true love.
