In August, Osbourne was reportedly involved in another altercation, but this time the other person wasn’t a stranger. The former “Osbournes” star allegedly got into a fight with his ex’s new boyfriend while he was still trying to rebuild their relationship. No charges were filed as both men were uncooperative with police.
