The 23-year-old singer has lines from her track 'Who You Are' etched on her hip but she misspelt a word when she gave the design the artist.
She said: "I wrote it out wrong. It says, 'Don't loose who you are in the Blur of the stars.' Loose, not lose. My fault.
"My mum cried! Typical me. It's not perfect but that's what I'm about."
The 'Price Tag' hitmaker also admitted she was shocked when she recently met a fan who had her name tattooed over his heart, because she worries he will eventually change his mind and find another artist he prefers.
She told Q magazine: "He got really tearful. I was like, 'What are you gonna do if you like Christina Aguilera's new album? Cross me out? He goes, 'You're my biggest idol.' Amazing. I've only been out for six months."
