While Nicole Scherzinger was busy knocking the socks off the audience in her amazing Julien Macdonald dress, Katy Perry left everyone scratching their heads as she stepped out on The X Factor grand finale stage in a VERY unflattering bird costume.
The enormous feathered peplum made her hips 10 times their usual size, while the boosted shoulders were akin to an American Football player.
We get that this is a stage 'costume' but it's more pantomime than prime time TV. Well, suppose it is Christmas...
And it wasn't just her outfit that set the Twittersphere alight - her vocals didn't go down too well, either, with the public and stars alike describing her performance as "flat", "scratchy" and "messy".
EEK. Better chalk this one up to experience.
