The touching celebration of the 51-year-old Brit, who is behind TV hit American Idol and whose celebrity roster of clients includes Annie Lennox, Lewis Hamilton, Carrie Underwood, and Pop Idol winner Will Young, has been published in a US entertainment magazine.
The Beckhams released a joint statement about the man who managed the Spice Girls back in the 1990s.
The celebrity couple tell The Hollywood Reporter: 'Simon has been our manager, business partner and close friend for 15 years… His passion and impact on charity around the world makes us enormously proud to know him and his beautiful family.'
Lisa Marie – the daughter of rock and roll legend Elvis Presley – also paid tribute to Fuller, who is her manager.
The 43-year-old singer says she is 'extremely lucky' to have him guiding her career.
She says: 'It is highly unusual in this business to find someone who makes things happen, who is powerful and intelligent, but who is also still incredibly humble, sensitive and creative… He has helped me change my life for the better in many ways...'
Prince Charles has applauded Fuller’s charitable work, which includes supporting his Prince's Trust.
The Prince of Wales says he is 'delighted to have this opportunity to pay my own tribute to Simon for all that he has done for my Prince's Trust and many other charitable causes.
'He has helped me stage several fundraising events and I can only say that his support and expertise have always been utterly invaluable.'
