In a post on the musician's Instagram, his family said with "profound sadness and very heavy hearts" that the rapper and hype man had died.

Earlier, the musician, famous for his 2003 hit Be Faithful, was seen collapsing on stage during a performance in Connecticut.

The New York-born rapper - whose real name was Isaac Freeman III - had taken off his shirt and walked behind a DJ booth when he appeared to fall.

"Last night, the world lost a radiant soul, a beacon of light on the stage and in life," the family said. "FatManScoop was not just a world class performer, he was a father, brother, uncle and a friend.

"He was the laughter in our lives, a constant source of support, unwavering strength, and courage. FatMan Scoop was known to the world as the undisputed voice of the club.

"His much made us dance and embrace life with positivity. His joy was infectious and the generosity he extended to all will be deeply missed but never forgotten."

Birch Michael - known as Pure Cold - also announced the musician's passing, and said in his statement: "You taught me how to be the man I am today.

"I love you Scoop, thank you so much for everything you gave to me."

Scoop's talent agency MN2S also paid tribute to "our dear friend and client," and added: "Scoop was a beloved figure in the music world, whose work was loved by countless fans across the globe.

"His iconic voice, infectious energy and great personality made an indelible mark on the industry, and his legacy will live on through his timeless music."

Sharron Elkabas, one of the founders of MN2S, said: "I spoke to him just a few days ago, and he was in such good spirits. It's hard to believe he is no longer with us."

Scoop is also known for his feature on Mariah Carey's Grammy-nominated song It's Like That, and for his collaborations with Missy Elliot, Nick Cannon, Skrillex and Timberland.

He was also known to UK audiences after appearing on Channel 5's Celebrity Big Brother: UK vs USA in 2015, and was the third housemate to be evicted.

The rapper was scheduled to perform in the UK in September at the Reminisce Festival in Saint Helens, who said on Facebook: "He was not just one of our most popular performers, he was a cherished member of the Reminisce family.

"His energy, talent and infectious spirit will be missed more than words can express."

Lauren Garrett, the mayor of Hamden, wrote on Facebook earlier on Friday: "Tonight, while performing at Hamden Town Center Park, Isaac Freeman, aka Fatman Scoop, had a medical emergency on stage.

"He is being transported by ambulance to the hospital. We will provide updates when they are available. Please keep him in your thoughts and prayers."
