It's not every day the prime minister comments on pop. But in a recent interview, David Cameron said his children have "appalling" music taste - because they're Katy Perry fans.
He claimed his kids' choices, such as Perry and Bruno Mars, were beginning to "infect" his iPod.
Perry has had a mixed week. Following the announcement of her split from husband Russell Brand, the US pop star has dropped out of her scheduled appearance at the People's Choice Awards this evening, despite being nominated for seven gongs.
She has tweeted her apologies and thanks for the continuing support of her fans - presumably a tweet of support has not been forthcoming from No 10.
While the Fireworks singer might not quite be to Cameron's taste, he is a big music fan, most recently giving a shout out to Lana Del Ray and Band of Horses.
Katy Perry's camp have yet to comment on Cam's remarks.
