BRITAIN’S Got Talent boss Simon Cowell is being sued over a £75million deal said to have been written on a napkin.
The TV and music mogul is accused by former business adviser Ian Rosenblatt of being unpredictable and “very difficult to speak to” as he refuses to own a mobile phone.

Mr Rosenblatt worked for Mr Cowell from 2018.
But he is pursuing him for millions after claiming a deal, originally hashed out over dinner on a serviette, was not honoured.
The pair are said to have met for dinner in London in October 2022 to discuss a way forward following a series of rows.
Documents submitted to the High Court claim that Mr Cowell offered an attractive fee arrangement for a deal he was working on at the time.
The documents say: “The terms of that offer were written on a napkin which Mr Cowell then signed.”
It offered up to 15 per cent of any deal of more than £75million.
The deal was later formalised at a meeting at Mr Cowell’s Cotswolds home in February 2023.
Mr Rosenblatt claims to have not been paid at all for the agreement.
Lawyers for BGT and X Factor boss Mr Cowell are yet to respond to the claims.
The Sun on Sunday has contacted him for comment.
