One Direction singer Liam Payne says his new year's resolution is to give up smoking.

Payne has set his resolution to "grow up" and stop the bad habit but admits it will be tough, reports people.com.

`I'm going to try and give up smoking, which is hard, but I do want to. I want to. It's about time. Need to grow up now,` he said,

Payne's bandmate Niall Horan has an equally health-driven goal for 2016, to spend more time training in the gym.

"I'm going to train, succeed in the gym this year. I always do it when I'm on tour and then when I get home, I'm c**p," he said.

"Yeah, I would like to succeed properly and get the job done."
