Nicole Scherzinger was ordered to leave the 'X Factor' house after partying until 2.30am.
The former Pussycat Dolls singer arrived at the London property on Monday to help her remaining acts Hannah Barrett and Tamera Foster choose their songs for this weekend's show, but the fun-loving judge and all the remaining acts stayed up dancing in Rough Copy's room until the early hours of the morning, when producers asked her to leave so the hopefuls could get some sleep.
A source told The Sun newspaper: "Nicole knows how to have a good time and she and the remaining contestants partied until 2.30am in Rough Copy's bedroom, dancing and twerking to her new music."The Rough Copy boys are known as the big party animals in the house and they have a beat box in their room which is right in the centre and where everyone congregates.
"Everyone was letting their hair down after a stressful few weeks, particularly Tamera who was missing Sam [Callahan].
"Things got pretty wild with a lot of loud music."
Despite the high spirits, insiders insist no one was drinking at the party as so few contestants are of the legal age to consume alcohol.
The source added to The Sun newspaper: "Sam Bailey doesn't touch booze while the only others legally allowed to drink are Rough Copy. Nicole could, of course."
