Normally, people wear fun fancy dress to stand out in a crowd, but X Factor star Olly Murs has revealed he uses it to hide from his fans.
The singer, who could hit number one in the charts this weekend, told the Daily Star he resorted to wearing a costume at V Festival so he didn't have to continually pose for photographs.
He dressed up like comedy character Fonejacker for the day, putting sunglasses and a balaclava on so he would be unrecognisable.
"It was weird … but I managed to have a good time and show my mates that I haven't changed," Olly commented.
The disguise was obviously a good way to hide, but he probably got a little bit hot by the end of the day!
If Olly wants another outfit to hide under, he could always choose Simon Cowell fancy dress - surely nobody would dare approach The X Factor's meanest judge for a piccy!
