Britney Spears has recruited a mystery celebrity to narrate her audiobook.

The "Toxic" hit-maker will release her highly-anticipated memoir The Woman in Me later this month and although she has been recorded reading a portion of the book, the rest of the voiceover will be done by someone else.

Sources told TMZ Britney found it too painful to retell the sections about her family in her own words, so publishers went on the hunt for an alternative.

Only female celebrities were approached for the job, and though the publisher pushed for Reese Witherspoon to do the narration, the Morning Show actress was unavailable.

It is believed the mystery star has completed work on the recording.

The "Lucky" singer recently explained that the book, which takes its title from a lyric from her 2001 hit "I’m Not a Girl, Not Yet a Woman," is the result of extensive therapy

She told fans on her Instagram: “Ok guys so my book is coming out very, very soon.

“I worked my a-- off for this book, I had a lot of therapy to get this book done, so you guys better like it. And if you don’t like it, that’s fine too.”

Britney is the third member of her family to release a tome telling the story of her rise to fame, with her mother Lynne Spears penning Through the Storm: A Real Story of Fame and Family in a Tabloid World in 2008 and her younger sister Jamie Lynn having published Things I Should Have Said in 2022.

Britney said in a message alongside the cover reveal of the book: “It’s coming. My story. On my terms. At Last. Are you ready? On sale 10.24.23.”
