The "No Problem" hitmaker said he is so ashamed of the chest tattoo that he tries to hide it as much as he can, reported Contactmusic.
"It's a backwards tattoo. It says, 'Get back to work'. Basically, it's a reminder that I'm not doing enough," the 23-year-old said.
The Grammy award-winner had always planned to live "a life with no tattoos", but he was in Germany when he agreed to get inked during an impromptu salon visit - and he regrets that decision every day.
