She's cute, loves pink and her song's called 'I Kissed A Girl', it's Katy Perry!

Katy's held on to that top spot in the US for the fifth week in a row, keeping Rihanna with 'Take A Bow' out in the cold (otherwise known as no. 2).

She's been bigged up by Madonna - of all people - on the radio and we can't wait for her UK debut.

The single's out here on the 1st September, with the album, One Of The Boys following a couple of weeks later on 15th. But if you can't wait till then, here's the YouTube video (good old YouTube). We think it's fun and uber catchy. Enjoy, and let us know what you think!
