It has been claimed that Jamie punched Matt Baker, Kym's ex-boyfriend who she broke up with just last week, during a bust-up at Manchester night-club Panacea over the weekend.
"Matt’s a tough guy but it caught him completely by surprise. When he went to retaliate a group of guys stopped it."
The newspaper claims that after being separated and given time to cool off, he later went to launch a second attack on Matt, but was stopped by staff at the club who then escorted him out of the premises.
The Mirror claims Jamie will also be contacted by the police, though officers were not called to the night club following the alleged incident.
Matt, a personal trainer, dated Kym for six weeks following her divorce from 'Hollyoaks' star Jame.
He and the 'Corrie' actress reportedly split up as Kym wasn't ready for a serious relationship following her public divorce.
