Jessie J always makes the headlines in her crazy catsuits and she always has us playing the ‘What colour hair will Jessie have next’ game. But it looks like the 23-year-old singer has run out of ideas and begun swagger jacking from US popstar Katy Perry.

As Jessie J performed her new single Domino on the American X Factor, she seemed to have gotten into the American spirit by stealing some inspiration from California Girl Katy Perry.We’ve seen Jessie J wearin loads of different coloured wigs, but never blue and despite the fact that she had to wear some hideous boots, she still pulled it off.

So who do you think rocks the Marge Simpson better? Jessie J or Katy Perry?
