On last night's episode of I'm A Celebrity...Get Me Out Of Here, Kerry Armstrong broke down in tears as she opened up about the terrible attack on her son.
The Aussie actress spoke about the moment her son, Callum, was attacked by a group of boys when he was younger, which caused him to now have brain seizures.
Callum's brother, Jair, ran to help him but was too late and 'not strong enough' to defend him, leaving him traumatised.
Kerry told Jackie Gillies and Danny Green, 'Cal went to stick up for a kid and Jai [his twin brother] wasn't near him. By the time he got into the room, Cal was getting his head kicked in.
'Do you know one of my boys, his personality changed forever. What he saw, he saw his brother just kicked and he couldn't - he wasn't strong enough to help.
'The one that got kicked in the head, he's the one that has the seizures.'
Professional boxer, Green, responded: 'That would be so hard to see, for a brother to see, and not to be able to do anything about it. It would be very tough.'
