Katy Perry summer anthem I Kissed A Girl has not lost its cheeky appeal after scoring a sixth week atop the U.S. single charts.

The sexy star has kept lovebirds Rihanna and Chris Brown from the top spot on the Billboard Hot 100 - Rihanna's Take A Bow remains at two, while Brown's Forever jumps up a spot to three.

But the Umbrella beauty has little reason to feel gloom, she is also sitting pretty at number four in the top five with her latest track Disturbia.

Lil Wayne's huge hit Lollipop has finally fallen out of the top five, leaving Coldplay's Viva La Vida to take the fifth position.
