British Prime Minister David Cameron 'hates' the 25-year-old's pop-tastic music (according to PerezHilton.com) and isn't afraid to admit it!
In an interview with the UK's Daily Telegraph, Cameron said the "appalling" music choices of his children, including Katy Perry and Bruno Mars, are "beginning to infect my iPod".
Ouch! Maybe this is a nationalistic response to American Katy's forthcoming divorce from British native, Russell Brand? Although we'd expect Cameron to be a little more diplomatic when it comes to foreign affairs.
Hilariously, the British PM also 'proudly' admitted he's finished the "Angry Birds" computer game, and is keen on playing "Fruit Ninja" on his iPad.
