According to a report on NEWS.com.au, the singer forgot the words to the second verse of her current hit Fly on the Wall, during a live performance on the UK variety show Ant and Dec's Saturday Night Takeaway.

Reports on entertainment websites said that Cyrus didn't seem bothered by the blunder, mouthing to her back-up dancers, 'I forgot the words!'.

However her fans were outraged, sparking heated debates on blogs and fan sites, with the most negative coming from the site mileycyrusfever.com.

UK newspaper The Sun reported that Cyrus was flown to the gig in a private jet that cost more than $314,000 to hire.

This latest incident comes after Cyrus was pictured making 'racist' actions in a photo that offended Asian people. -- The Sun, NEWS.com.au
