The nation seems to be obsessed with Harry Styles' love life thanks to his relationship with Taylor Swift, so you could be forgiven for forgetting what his day job is.
But on Monday the One Direction heartthrob was back to work, filming with his band mates in London.
The quintet were seen working their magic in front of the camera, on the banks of the River Thames.
Harry was seen with a brooding look on his face, hiding under a flat cap with his hands stuffed into his pockets.
Louis Tomlinson was seen holding out his hand, while the others tried to act aloof by gazing into the distance in different directions.
The boys battled with the cold temperatures and the film had a distinctly moody feel to the video, in stark contrast to the lighthearted attitudes seen in the Kiss You video.
While Harry might be on set in person, his mind might be elsewhere and he is said to be smitten with Taylor Swift.
Harry's good friend Radio 1 DJ Nick Grimshaw thinks that the British singer may have found the one in Taylor.
Nick told The Mirror: 'Harry really likes Taylor, he’s fallen for her in a big way.
'At first I wasn’t sure if the relationship was a real one but I talk to him a lot and it seems to be that she’s the one – for now, anyway.'
Just hours after dropping Taylor off at the airport over the weekend Harry was seen turning up to a friend's house party in Leeds.
The singer stunned guests when he arrived at the bash and was seen helping with the washing and posing for pictures with female fans.
