I am flabbergasted that Leona Lewis is representing the UK for the Olympic handover

If I was the UK decision-maker and was FORCED to send a pop star to represent at the Beijing handover, here are some other ideas I would've floated: David Bowie, George Michael, The Spice Girls reunited, Coldplay, Boy George and the Culture Club, The Rolling Stones, Mick Jagger all by himself, Rod Stewart even, I don't know, Oasis? The Pet Shop Boys? Depeche Mode? Anybody else but Leona Lewis. Is this part of her package deal for winning X Factor? Is Simon Cowell really that powerful?
