Pop Superstar?

Pop newcomer Mika has scored his debut UK number one hit, ending X Factor winner Leona Lewis's reign at the top.

Beirut-born, London-based Mika, who topped the BBC's Sound of 2007 poll earlier this month, has risen two places with his single Grace Kelly.

Lewis slipped to number six after four weeks on top with A Moment Like This.

And Doctor Who star Billie Piper's 1999 hit Honey to the Bee appeared at number 17 thanks to new chart rules after a campaign by BBC Radio 1's Chris Moyles.
