The hot Pussycat Doll became more act than judge for a moment when she was introduced at the beginning of the show.
Fists pumping and looking very excited, the 35-year-old's antics caused a mixed reaction amongst the audience.
Twitter went into a frenzy, with one user writing:
'Sit down Nicole. You're drunk. Again.'
While another tweeter hit back with:
'Nicole Scherzinger was not drunk last night she's just very American.'
With all the kerfuffle surrounding the singer, X Factor were forced to issue a formal comment, stating:
'Nicole wasn’t drunk. She was just excited and getting into the disco spirit.'
