The 23-year-old country starlet refuses to be corrupted by the glitzy celebrity lifestyle and said the only place she goes wild is on stage, reported Contactmusic.
"I'm not a party girl. I love performing on stage, that's where I can really come alive and get a bit wild, but in private I want to live more quietly. I want to live a good life, make good choices, and be good to the people I love and stay close to my friends," she said.
The 'I Knew You Were Trouble' hitmaker, who is dating One Direction hunk Harry Styles , said she does not want to have her mistakes played out on camera and she is too conscious of her pristine and clean-cut image to let herself go in public.
"Sometimes people tell me that I'm young and I should be going out more, having fun, making mistakes and being more selfish. The trouble is, if I mess up there'll be six months of headlines afterwards."
