Piers Morgan has paid tribute to his "kind friend" and manager John Ferriter who has died aged 59.
The celebrity manager, who also counted Jimmy Kimmell, Ryan Seacrest, Peter Andre and Gemma Collins among his famous clients, died on Thursday night.
Piers wrote online to his 6.7 million followers: "RIP John Ferriter, 59.
"My brilliant manager and ferociously loyal, kind, charismatic & supremely talented friend.
"I trusted him with my life, and he enriched my life so much.
"Thank you John, for everything you did for me, and for my family."
Piers's co-host on Good Morning Britain Susanna Reid added: "So sad. I knew John briefly but long enough to know he was loyal, determined and great company. Devastating news.
"Hard to believe. Huge love to all of John’s family and friends."
Mr Ferriter launched management and production company The Alternative after 19 years at PR agency William Morris.
He was described as being the best at "transplanting British stars to the US audience".
