American musician Katy Perry is undoubtedly one of the most popular performers in world music today!

The singer sure knows how to captivate her audience and keep their attention all through the show. It isn't just that she is lively and full of energy... well, it is that too.

However, what really stands out is her sense of style... to be more precise, her innovative costumes and hair colours that seem to really bring a spark to whatever stage she is on!

If you don't know what we're talking about, cast your mind back to her performance at the recently concluded 25th Nickelodeon Kids' Choice Awards... or look out for photos of her performance at the opening ceremony of cricket's Indian Premier League, on 3 April!
