Britney Spears says she has no plans to return to music despite reports the Toxic hitmaker was plugging younger artists to help her with a new album.

In an Instagram post shared on Thursday, the 42-year-old addressed rumours she tapped pop singers Charli XCX and Julia Michaels to pen new songs for an upcoming album, writing “most of the news is trash”.

“They keep saying I’m turning to random people to do a new album … I will never return to the music industry,” Spears wrote.

“When I write, I write for fun, or I write for other people!”

The singer stated she “honestly enjoy[s]” being a ghostwriter – someone who writes material credited to another author – and has written 20 songs for other artists in the past two years.

“For those of you who have read my book, there’s loads that you don’t know about me … I’ve written over 20 songs for other people the past two years,” she continued.

“People are also saying my book was released without my approval illegally and that’s far from the truth … have you read the news these days ??? I’m so LOVED and blessed !!!”

The rumours were originally reported by Page Six and The Sun, with the former outlet writing Charli and Michaels were “among the lyrical savants who have been tapped to pen tracks for what Spears’ team hopes will become the Princess of Pop’s first full-length release in nearly a decade.”

Spears released her last album, Glory, in 2016.

Spears has previously worked with Michaels in the past for Glory, with Michaels credited as a songwriter on tracks Better, Just Like Me, Just Luv Me, Invitation, Change Your Mind (No Seas Cortes), Slumber Party, and Do You Wanna Come Over?

In an interview with People Magazine at the time, Michaels described Spears as “active” in the recording studio.

“A lot of the songs that her, Justin [Tranter] and I did together were her concepts, melodies and lyrics. I think the pop melody sensibility is so engrained in her brain that she just sounds like pop music,” Michaels said.

“She is exactly what you think she’s like. She is really down to earth, really humble, just wants to make music and have fun. She’s no different from anybody else.”
