One Direction's Liam Payne got MAJOR backlash after posting this pic!

The One Direction boys are growing up and they want you to know it. Case in point: Liam Payne posting a picture of himself smoking a cigarette on a private jet.

Liam posted the black and white image onto his Instagram account, and his 6.7million followers are NOT happy. “Smoking gives you lung cancers and if you keep it up you'll die in the next 10 years and absolutely nobody wants that,” said @fuzzybird369. “I love you more than anything in this world, but I really hope that your smoking decreases because it's not good for you nor your health. I’m saying this not to hurt you at all, but to protect you and guide you to a healthy life,” pleaded @alexpesaaa.

Not setting the best example, are you, Liam?
