Washington, Oct 30 Andrew Morton, the controversial biographer, has slammed reports that his latest book on Angelina Jolie's life suggests the actress romanced her mum's lover.

Ever since the British writer has started writing his tome on the 'Tomb Raider' star, tongues have been wagging over what information the book throws up.

Morton has insisted that the book will be a great read, but it doesn't claim that the actress slept with her late mother Marcheline Bertrand's live-in lover when she was just 16 - a fling that allegedly destroyed the relationship.

"It's about as true as I'm sitting on this horse," Contactmusic quoted Morton as telling Life and Style magazine.

The author has not revealed what he's gathered for his book.

Morton has also penned exposes about Princess Diana and Tom Cruise. (ANI)
