Buchanan planning candid Sugababes book?

Keisha Buchanan has reportedly opened talks about penning a tell-all book on her time in Sugababes.

After being ousted from the girl group last year, insiders claim that the singer is now weighing up the idea of releasing a candid publication about the tensions within the band.

"Keisha's in discussions about writing a book about her time in the band," a source told Now. "Publishers have been after her for ages, but it's only now she's seriously considering it.

"At the moment it's still in the initial stages, but she's very excited. The book will chart the highs and lows and obviously deal with the very public split last year.

"Keisha's always kept quiet about what really happened even though the others have spoken at length about it."
