A biography about Elvis Presley is sensationally claiming he was a paedophile who preyed on underage girls.

According to author Joel Williamson, in his 2014 book Elvis Presley: A Southern Life, while on tour aged 22, the king of rock had a string of girlfriends as young as 14.

Williams even goes on to say that Elvis once slept with a young fan and took her to hospital as his condom broke during sex.

The Sun newspaper also reports that Williamson details an incident with three young 14-year-old fans who the singer befriended.

The author is a noted historian and says Elvis would have pillow fights, tickle, wrestle and kiss the girls.
