Simon Gregson's wife reportedly had her nose broken as she defended her brother from a gang.
The 'Coronation Street' star's partner Emma Gleave, 35, is said to have been on a night out with her sibling - who has learning difficulties - when she tried to stop when an "awful man starting goading him".
A source told The Sun: "Emma has always been hugely protective of her brother. The two of them had done nothing wrong when this awful man started goading him.
"Emma wasn't prepared to let that happen and tried to defuse the situation -- but the next second she was punched in the face and left in a lot of pain with a bloody nose."
It's said the 44-year-old Steve McDonald actor is "furious" over the alleged incident, but his focus is on making sure his wife - with whom he shares sons Alfie, 11, Harry, nine, and three-year-old Henry - is looked after.
The insider added: "What sort of bloke punches a woman? Simon was furious. If he got his hands on this bloke, God knows what would happen. But his first concern is for Emma."
The report comes just days after fellow soap star Katie Jarvis - known to 'EastEnders' fans as Hayley Slater - updated her own fans after she was "glassed" on a night out last week.
She tweeted: "OK to put people's minds, and questions to rest. I am absolutely fine thank you so much for all your concern and checking in on me but I'm a solider and been through hell of alot worse. (sic)"
Katie originally posted - and later deleted - tweets about the alleged attack on Friday night (08.03.19) in east London, and at the time she thanked medical staff for taking care of her.
She wrote at the time: "Big thank you to the Met police tonight and ambulance service for looking after me after I was glassed by a drunken Irish man for f*** all."
Although she later deleted her posts about the incident, the 27-year-old actress thanked her fans for their kind words and added she was "good as gold".
