Olly Murs reveals 'nappy rash'

Olly Murs has revealed the truth behind his Comic Relief nappy rash.

When Olly took a trek through the African desert for the charity there were reports he was suffereing from 'chaffing'.

Setting the record straight, he tells Digital Spy: '(there was) massive chaffing! I had some Sudocrem and it said it was for nappy rashes!

'I was chatting for an interview and told him I had a nappy rash- as that's pretty much what it was. I had it all down the front.

'And when you're walking for nine to 10 hours a day, it was hurting. We're talking about serious pain.'
