One Direction teen heart-throbs Niall Horan and Zayn Malik - who has had to skip some of the group's US tour dates because of a bereavement in his family - were recently filmed by a fan having a good ol' smoke outside The Ballroom restaurant, in Canada. Whilst it's well known that Mr Malik smokes like a chimney, this is the first time we've had any knowledge of Niall sharing his habit.
Not exactly the best habit to pick up, is it Mr Horan? Especially when you've got braces (likely to result in teeth staining) and when you're day-to-day is singing for a living.
Fingers crossed the habit doesn't spread to their other band members, and doesn't last too long! Check it out:
