Nicole Scherzinger partied with X Factor contestants until 2.30am, and ended up being ordered to leave the house they share.
The former Pussycat Dolls singer arrived on Monday to the London property 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, at which point producers asked her to leave.
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."
