They are known for being clean-cut popstars, but One Direction reinvented themselves for the X Factor final on Saturday night.
The chart-topping five-piece, who won the ITV talent show in 2010, wore all-black outfits for their live performance at London's Wembley Arena.
But, despite getting an audible reaction from fans, their appearance divided wider opinion.
Together, the boys - Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - wore matching, black skinny jeans with rock 'n' roll-inspired tops.
Harry opted for a classic shirt, while Liam and Zayn wore structured jackets. Louis kept it simple with a T-shirt, while Niall wore a scoop-neck top under black shirt-jacket.
The quintet looked comfortable in their new, edgier look - but it was greeted with a mixed reaction.
Singer Boy George took to Twitter to declare: 'Harry looked like a young Keith Richards!' before adding: 'Liam looked quite....messy!!'
Meanwhile, former Loaded editor Martin Daubney said: 'Harry the headband is the next step to your inexorably morph into Mick Jagger. Espadrilles next.'
Billie Faiers then said: 'Is it me or do one direction look really old all of a sudden ?? Haha'.
Speaking to host Dermot O'Leary, Harry said he was looking forward to some well-earned time-off over the festive period. 'We've got christmas off. I'm a turkey guy, everyone is,' he joked.
The 19 year-old then added that he won't be exchanging mutual gifts with his band-mates for the holiday season: 'We're not very good at presents for each other.'
Liam chimed in: 'We're absolutely sick of each other, so we won't be with each other.'
But fans shouldn't expect them to be away for too long. Niall said: 'We're back on tour in April to South America and then next door at Wembley Stadium in May.'
