Jessica Ennis "embarrassed" to read Fifty Shades of Grey

Olympic heptathlon champion Jessica Ennis has admitted that she felt "embarrassed" to read E. L. James's erotic novel 'Fifty Shades of Grey'.

The 26-year-old says that she could only read half of the second book in the trilogy.

"When I got back, my mum asked to read them and she's read all three, but I was embarrassed," Ennis told the Daily Mail.

"I kept folding it over so no-one could see what I was reading."

The Sheffield-born athlete added that she found the books "quite raunchy".

Ennis has been shortlisted for this year's BBC Sports Personality of the Year award.
