Exact details are unclear but the former rugby league is believed to have died over the weekend, after being found collapsed at his Warrington home. The cause of death is unknown.
Reports claim George was taken to hospital where doctors were unable to save him, with his brother telling the Sun: “We just heard he has passed away. We’re all in shock. We don’t know much.”
Kerry and George knew each other as teenagers but began dating after meeting again in 2012.
They welcomed a daughter, Dylan-Jorge, in April 2014 and married five months later.
The couple split in 2015 and divorced two years later.
While George moved away from the limelight after the split, he previously spoke openly with the press about his mental and physical health issues.
In 2014, he was detained under the Mental Health Act after an incident in the street outside the home he shared with the former Atomic Kitten star.
Weeks later, he said his actions outburst was fuelled by a mixture of alcohol and pills, telling The Sun on Sunday: “I wasn’t sleeping, so I was taking sleeping pills and I’d been drinking and taking steroids. I’d been up for the best part of four days.”
