In an Instagram post, the popstar, 40, said the time spent under the controversial arrangement "really hurt me" and was "set up to make me fail".

Last month a judge terminated the conservatorship which had allowed the singer's father and team to control her life and money for more than a decade.

She called the life-changing ruling the "best day ever".

Lawyers acting for her father have called for her to continue paying his legal fees, claiming that he had "stepped up" to protect her from "opportunistic and wholly self-interested parties".

In her post on Monday, Spears said she decided not to release new music as a way to get back at the people she said were hurting her.

"I wanted to be nice but what they did to my heart was unforgivable," she wrote.

"I asked for 13 years to perform new songs and remixes of my old songs...and every time I was told, 'No...'

"It was a set up to make me fail.

"So much wasted time and I guess it seems odd to most now why I don't even do my music any more.

"People have no idea the awful things that were done to me personally...and what I've been through I am scared of people and the business.

"They really hurt me.

"Not doing my music any more is a way of saying "F*** You" in a sense when it actually benefits my family by ignoring my real work."

The last album Spears released was Glory in 2016.
