The pair were later moved temporarily to a budget hotel after Rylan gave the paps a shot of his bare backside.

A source told The Mirror: "Tulisa was disappointed with Lucy - she had her down as a serious musician and a real competitor for this year's title but now she thinks she's just here for a laugh.

"They really embarrassed themselves. Photos of them rolling around drunk in the street appeared and it really brings the show into disrepute."

However, an XF insider told MailOnline: "All acts have been warned to concentrate on the competition."

Tune in to ITV1 tonight at 8.20pm for The X Factor.
