In a statement, Dickinson, 61, who now lives with fitness instructor Liana Dolci in Paris, said: “This is a terrible tragedy which appears to be a tragic accident.
“Our children Austin, Griffin and Kia and I are devastated.
“Out of respect for Paddy we won’t be making any further comment at this hugely difficult and painful time for our family.”
Paddy, who was in her 50s, and Bruce got married in 1990 after being together for two years.
But they split – after almost 29 years of marriage – in 2018, with news of the separation only emerging last November.
FOUND DEAD AT HOME
Dickinson was left facing a huge divorce bill after starting a relationship with fitness instructor Liana, 15 years his junior.
The Run to the Hills singer and Iron Maiden superfan are now understood to live together in France.
Dickinson’s split from Paddy came four years after he beat stage three throat cancer after being told he had two tumours on his tongue.
He was supported by his wife and their three children – Austin, 29, Griffin, 27, and daughter Kia, 28 – throughout the ordeal.
The frontman was later given the all-clear after six months of intense chemotherapy and radiation treatment.
Bruce told all about his health battle in his 2017 autobiography “What Does This Button Do?”
And he revealed to Rolling Stone magazine how surviving cancer had given him a new appreciation of life.
HUGE DIVORCE BILL
He said: “Living is living now, every minute, every second, for right now.”
Iron Maiden were formed in Leyton, East London, in 1975.
They have gone on to sell 80 million albums worldwide – making them one of the most successful heavy metal bands of all time.
London Ambulance Service confirmed they had attended, but said the patient was pronounced dead on arrival.

A spokesperson said: “We were called at 9.42am today to reports of a person unwell in Chiswick.
“We sent two ambulance crews to the scene – the first one arriving within two minutes.
“Sadly, the patient had already died.”
