X Factor stars Mitsotu have revealed the naked antics that went on at bootcamp.
The trio, who made judges' houses with Louis Walsh, said this week that the contestants were given a 'free for all' party on the first night of bootcamp in Liverpool.
Mitsotu singer James Collins told the Metro: "People were running down corridors naked. It was crazy. People were hooking up everywhere.
"Everyone was trying to show off their X Factor in all senses."
A "shocked" James added: "We set our own rules."
However when it comes to judges' houses, it's a very different story.
James and his bandmates - Holly Cooper and Jimmy Essex - traveled to Las Vegas to compete for a spot in the live shows.
He explained: "here was a 'Prince Harry warning', Louis told us not to party."
The group - whose name stands for Music is the soul of the universe, added that they hoped the show would finally provide them with their big break.
The X Factor 2012 judges' houses air this weekend on Saturday and Sunday on ITV1.
