The 22-year-old pop star has decided to "grow up" and live a better and healthier life, reported People magazine.
"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. 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 crap. Yeah, I would like to succeed properly and get the job done," Payne said.
One Direction are set to go on a hiatus next year for at least two years.
