Britney Spears has "voiced her intention to officially retire" according to her long-time manager, who has resigned, saying his "professional services are no longer required".
Larry Rudolph, who has worked with Ms Spears for more than 25 years said: "I wish Britney all the health and happiness in the world, and I’ll be there for her if she ever needs me again, just as I always have been."
The 39-year-old pop star has been under a conservatorship since she suffered a mental health breakdown in 2008, with decisions about her finances and personal care being managed by her father Jamie Spears.
In a chilling testimony last month, she said she was "not here to be a slave" and claimed that she was forcibly kept on contraception, made to perform against her will and given lithium – a mood stabilising drug.
Despite the claims, a judge in Los Angeles denied Ms Spears’ request to remove her father from his role.
In a letter to Jamie Spears, obtained by Deadline, Mr Rudolph said: "It has been over 2 1/2 years since Britney and I last communicated, at which time she informed me she wanted to take an indefinite work hiatus.
"Earlier today, I became aware that Britney had been voicing her intention to officially retire.
"As you know, I have never been a part of the conservatorship nor its operations, so I am not privy to many of these details. I was originally hired at Britney’s request to help manage and assist her with her career. And as her manager, I believe it is in Britney’s best interest for me to resign from her team as my professional services are no longer needed.
"Please accept this letter as my formal resignation.
"I will always be incredibly proud of what we accomplished over our 25 years together. I wish Britney all the health and happiness in the world, and I’ll be there for her if she ever needs me again, just as I always have been."
Mr Rudolph has been credited with helping Ms Spears become an international superstar, guiding her since 1995 through a career which included the hits "baby one more time" and "toxic".
