She’s already published a best-seller with her racy coffee table book Sex. But now Madonna has teased she plans to reveal all her secrets in an autobiography.

But don’t get too excited – she’s not quite ready to tell all just yet.

Madonna, 56, told Radio 2: “I’m sure I will [write an autobiography] one day. I’ve got so many tales to tell.”

From feuds with Sir Elton John and Lady Gaga, to her marriages to Sean Penn and Guy Ritchie, Madonna certainly has a lot of stories up her sleeve.

And she admits she has a lot more to tell than she reveals in her music.

Madonna said of her songs: “They’re just one slice of my life.

“If I wrote my book that would be from start to finish, and that’s a whole lot of ground to cover.

“I’d tell the stories I felt were valuable to tell, that were inspiring, that people could relate to.

“I’m a storyteller, that’s what I think of myself as.”
