Shortly after he and his girlfriend Cheryl welcomed the birth of their son Bear in March, Liam Payne revealed that he'd quit smoking for the sake of his offspring.
But when the former One Direction star shot a music video for his new single Get Low on the streets of central London on Tuesday, he was spotted indulging in his old habit once again.
The Strip That Down singer openly puffed away as he took a break from his high-energy shoot - just three months after stating that kicking the habit was something he felt compelled to do, as it's 'not right' to smoke with a son.

'People were hacking my friends' phones. I was p***ed. [Though] I kind of knew what I was getting myself into. She is one of the most talked about people in the world, but I had no idea how much that would change my life.'
