Let it go Dave.

The prime minister has done an interview with Heat magazine and in between telling us he likes Marmite and that he's related to Kim Kardashian (would that account for all the selfies?) Mr Cameron confessed to being a fan of Frozen.

He told the magazine: "I can virtually recite it all, I mean, that's in the car so I'm not going to sing that now…!

"I have watched Frozen, I can see it's brilliantly done.

"I mean for four-year-old-girls, they love it."

Not just four-year-old girls apparently.
