Mel C planning an autobiography

London: Former Spice Girl Melanie Chisholm is planning to pen a book about her life. The 40-year-old singer, who plans to reveal the band`s secrets in a tell-all book, said she wants to wait for sometime so that she does not get into trouble with her former band mates - Geri Halliwell, Emma Bunton, Mel B and Victoria Beckham, reportedly.

"Of course shenanigans did go on (in the 1990s) but I`m not going to share them. I`m going to save them for my book when I`m 80.

"It`s not something that I`m inspired to do at the moment. But when I`m an old lady and I don`t mind who I upset, I might dish all the dirt then, I think we`ve all got dirt," she said.

Mel C, who last performed with the Spice Girls at the 2012 Olympic Games, said Victoria, 39, does not enjoy performing any more and is focused on her fashion career.

"I don`t think we`ll ever do anything which was as exciting or fantastic as the Olympics. Of course, us girls are very aware that Victoria doesn`t enjoy performing any more and that`s not her passion now, we completely understand that."
