Celebrity Big Brother and Arsenal Fan TV star Heavy D was reportedly discovered dead on his kitchen floor by his brothers this week.
The 47-year-old's death was announced on Wednesday - and according to the Daily Mail, the news came almost two weeks after he was last seen alive.
The Storage Wars star - known for his "Boom!" catchphrase - is said to have spent the night drinking and playing games with good friend Lorna Onabanjo in Leigh-on-Sea, Essex, before returning home.
The newspaper says that family members became concerned for his welfare and visited his home in North London on Wednesday morning, finding him dead on his kitchen floor.
"His family contacted me this morning because they'd been unable to contact him," said Onabanjo. "He usually saturates social media but there had been nothing for days.
"Some of his brothers went around to his home in North London and they saw his body through a window on the kitchen floor.
"At the moment it's suspected he died of a heart attack but we won't know until after a post-mortem. He was a big kid, and I'm really going to miss him."
Heavy D's former personal trainer Matt Fiddes wrote on Instagram: "He was on a real mission to improve his health and was making amazing progress. Getting into boxing and eating clean. And training so hard.
"I would imagine the closure of gyms and fitness facilities was tough on him for his physical and mental health. He lived for the progress he was making and his fight nights.
"Such a pleasure to be with and so nice to all my instructors and students. He always took the time out to greet them all."
The star - real name Colin Newell - is survived by two young children.
