Zoe Ball's boyfriend, was found dead in his South London home last night, leaving the presenter ‘completely and utterly devastated’.
Zoe, 46, starting dating the BBC cameraman after the breakdown of her marriage to Norman (Fatboy Slim) last year.
A Metropolitan Police spokesman confirmed the circumstances surrounding the death were "not being treated as suspicious".
The force said in a statement: "Police were called to a residential address in Putney, South London at 18.40 on Thursday 4th May, to reports of a man found deceased.
"Officers attended alongside staff from the London Ambulance Service, and a man believed to be aged 40 was pronounced dead at the scene.
"The circumstances are not being treated as suspicious, and the coroner has been informed."
A close friend also told The Sun: "Zoe is overcome with grief. She is completely and utterly devastated.
"Billy had made her happy again after the most horrendous year when her marriage broke down.
"This was completely out of the blue. She had no feeling that this was coming and is in total shock.
"As far as we know this occurred at his house in London and it was friends who raised the alarm. She’s going to need a lot of time to grieve.
"This just feels so unfair because Zoe had finally found happiness with Billy and had so many exciting plans for their future.
"It’s devastating. There’s nothing else other than devastation today."
Zoe has yet to publicly speak about his death but she recently retweeted a post from the Samaritans charity urging people to speak to someone if they were suffering.
Zoe also posted a beautiful photograph of a flower to Instagram earlier today with the caption: "My sweet love X."
