The former boybander surprised fans by playing the song in London

He may have moved on from One Direction, but Harry Styles isn't afraid to dip into the past every now and again.

The boyband heartthrob is preparing the release of his second solo album this Friday, but at a recent gig in London he went back to where it all started by performing 1D's debut single.

He surprised many by playing 2011 megahit 'What Makes You Beautiful' at the Capital FM Jingle Bell Ball, and it went down pretty well - even if it was turned into an indie tune. You wouldn't expect anything less, given his stylistic transformation in recent years.

Still, good on him for not being precious about his teenybopper roots (and for rocking that nail polish, too. The jury's still out on the sparkly jumpsuit.)
