Nathan was accidentally treated to Tom and Max in their birthday suits.
The Wanted's Nathan Sykes explains just how and why the boys exposed themselves.
"I’ve seen Tom and Max naked outside a toilet," he told Capitalfm.com in their live web chat.
Despite Max trying to intercept the story by shouting, "What happens in the band stays in the band," Nathan went on to spill the beans.
"'Hurry up, hurry up mate,' they were saying. 'We need to use the toilet’" Nathan confessed.
"And then when I came out they had their bums out."
