Geri Halliwell and Melanie B are set to embark on a war of words when their autobiographies hit the shops on the same day.

Both Mel B’s Catch A Fire and Geri’s Just For The Record are set for release on 2nd of September. Both books seemingly chart the end of the Spice Girls’ working relationship, and of Mel and Geri’s own friendship.

A literary industry insider said “This will be the biggest battle between Spices for years.”

“Mel is already pretty sure that Geri will sell more copies” added the insider “but she knows both books coming out the same week will bring tremendous interest and make people talk about the Spice Girls again.”

Just For The Record is the follow up to Geri’s bestseller If Only.
