X Factor contestant Jahmene Douglas has reportedly refused to perform a Katy Perry song on the ITV reality show this weekend as it glorifies drinking alcohol to excess.

The contestants were due to perform Perry's single 'Last Friday Night' as a group during this Sunday's results show (November 18). However, Douglas is alleged to have refused to perform the song, which has lyrics such as: "I smell like a minibar, DJ's passed out in the yard" and "Yeah we danced on tabletops, and we took too many shots, think we kissed but I forgot."

Speaking to The Sun, an un-named source claimed that the programme makers are trying to find a replacement song: "Bosses are desperately trying to find a new song for this weekend’s group ensemble after Jahmene’s refusal. The six remaining acts were supposed to perform Last Friday Night but Jahmene has said no."

The source added: "The song is about partying and drinking and Jahmene is teetotal. He has made it clear from the start that he won’t sing songs about drinking and when he heard this track he was adamant he wouldn’t perform it...Bosses have respected his wishes and it’s all hands on deck to get a new song ready in time for Sunday."

'Last Friday Night' is taken from Perry's 2010 album 'Teenage Dream' and features a video which sees Perry hosting a big house party and drinking until she passes out. Hanson, Kenny G, Corey Feldman, Debbie Gibson and Rebecca Black all guest star in the promo.

Goodness me.
