McCartney book high on 'sex and surprises'

Paul McCartney's former aide is vowing to include explosive sex stories and shocking revelations in his forthcoming biography on the ex-Beatle.

Geoff Baker quit as the Hey Jude legend's publicity guru in September, amid reports he'd fallen out with McCartney and his wife Heather Mills.

And now Baker - who was one of McCartney's main confidantes for almost 20 years - is working on a tell-all book, which he hopes will surprise his legions of fans.

He says: "The book is coming along well and there's going to be a few surprises in it for some people. There's a lot of sex involved and a few buried secrets will be unearthed.

"It centres around the world of celebrity and what they get up to in private. There are bound to be a few raised eyebrows."
