In the heat of his 1999 concert, Ozzy Osbourne, the Prince of Darkness himself, gives the audience a surprise they'll never forget. As he rocks out in his signature black attire, Ozzy bends over, letting his tight, round ass take center stage.

The stage lights catch the glint of his silver studded belt, accentuating every curve and dimple of his infamous behind.
