On Monday, Jack went to the home he still shares with Lisa. When things got more heated, Gabel tried to intervene.

TMZ reports that onlookers watched the argument grow more intense before Jack punched Gabel in the head then left the property.

Police were then called and a battery report was taken. No case has been filed as Gabel has not been co-operating with police.

The incident is still under investigation.
