All that glitters... Katy Perry may have shimmered in gold but voice failed to impress X Factor viewers
Pop singer Katy Perry may have shimmered like a star in a gold feather dress on The X Factor live final last night, but her vocals didn't exactly have star quality.
Katy failed to impress television viewers with her performance at London's Wembley Arena before former prison officer Sam Bailey was crowned the winner.
The 29-year-old singer was surrounded by dancers as she decended from the ceiling of the arena in a giant cage.
She sang her hit song Unconditionally but fans of the show on Twitter seemed unimpressed by the California girl's voice.
After the singer suffered pitching issues, one fan posted, ''Katy P should have learnt her lesson from last time and MiMED.''
Another added, ''What number do we call to vote Katy Perry off?''
