The 44-year-old performer decided to go on an indefinite hiatus from music just days after celebrating 25 years in the business, a Sunday Mirror report says.
She made the decision after sacking her long-term manager Terry Blamey, who was instrumental in launching her music career when she was just 19, the report said.
It blamed tensions between Blamey and Minogue's father for the bust up.
"Kylie's decision to stop recording for the time being and part company with Terry has come as a massive shock," a source close to the singer reportedly told the UK paper.
"Ever since she broke into the charts in the 80s Terry has been the man behind the scenes. But now Kylie is saying she wants to pull back from the pressures that come with a music career.
"She says she's determined to devote more time both to herself and to her career as an actress."
Minogue's decreased status at her new label Universal was also a factor in her decision to leave music, the paper said.
Her former label Parlophone has been sold to the corporation and Minogue was not getting the same level of attention among its extensive roster of performers, it said.
Minogue recently returned to acting with an appearance in the surreal French film Holy Motors.
She got her start in the entertainment industry with a part on the Australian soap Neighbours in 1986.
