George, who had a long history of drug abuse, was reportedly pronounced dead on arrival at the hospital on Friday.
Kerry’s former partner is father to her youngest daughter Dylan-Jorge, five, and the mother-of-five is ‘heartbroken’ over his death, reports The Sun.
A source close to Kerry told the publication: ‘Kerry was told this afternoon that George suffered an overdose and was taken to hospital, but was declared dead on arrival.’
‘No one yet knows what he overdosed on or whether it was intentional or an accident.
‘Kerry is heartbroken, he’s DJ’s dad and she loved him once. She can’t bear the thought of explaining to her daughter what has happened.’
MailOnline has contacted George and Kerry’s representative’s for comment.
Just weeks before his death, George shared an image of himself and Dylan-Jorge on his Facebook page alongside the caption: ‘Daddy loves you always xxx.’
Expressing her condolences to the late star, Big Brother’s Aisleyne Horgan-Wallace wrote on Twitter: ‘Omg this is so so very sad.’
Kerry married George in September 2014, months after giving birth to Dylan-Jorge however the couple divorced in 2017.
There had reportedly been a restraining order issued keeping George away from Kerry at the time of his death.
George and Kerry initially met during their teenage years at at Padgate High School in Warrington where they were childhood sweethearts.
The former couple rekindled their romance during their thirties while Kerry was on her book tour for Too Much Too Young and George worked as her security guard.
During their three-year marriage George battled mental health issues and Kerry later claimed that he had been violent towards her throughout their relationship.
She previously split from him in October 2015 after thirteen months together and a month later appeared in court accusing him of beating her up at their home, after allegedly arming himself with a Taser-style device and a knife.
However he was later acquitted after prosecutors revealed that they didn’t have enough evidence to secure a conviction.
A matter of months later, the pair first sparked reconciliation rumours when they were spotted out together with their daughter Dylan-Jorge.
The couple were so determined to make their relationship work and appeared on the reality show In Therapy last year to talk through their issues.
They even blissfully renewed their wedding vows in November 2016.
Speaking shortly after the reconciliation, Kerry insisted to OK! magazine that George ‘wasn’t a monster’ and they both had ‘fiery tempers’.
She explained: ‘There was never a restraining order, that was reported incorrectly.’
‘He was allowed to come and pick up DJ when he wanted. I’ve never felt threatened. I’ve been no angel in this either. I can get angry and mad, too’, she added. However, the pair officially called it quits and divorced in 2017.
Kerry is a doting mother to five – she has two daughters with ex Westlife partner Brian McFadden Molly, 16, and
and Lilly-Sue, 14.
She also shares Heidi, 10, and Maxwell, nine, with second husband Mark Croft.
