The 19-year-old singer wants to get the tattoo from him favourite tattooist Freddy Negrete on his next trip to LA, reported Daily star.
"He just can't seem to stop tattooing at the moment, but he's getting worried they're all too front-heavy so it's definitely his back we'll be concentrating on," Negrete said.
Negrete said that full-back inking will not be an overnight job and might take months.
"Harry will probably have more Hebrew lettering. He already has his sister's name in Hebrew on his arm and he loves it," Negrete added.
Styles already had a star with five points representing each member of the band etched on his arm.
