The body-art was revealed after 19-year-old singer's London-based tattooist Liam Sparkes posted a snap which went viral, reported Sun online.
While Styles' face cannot be seen in the image, some of his other unique tattoos make the singer easily identifiable.
His long list of body art includes swallows, his sister's name written in Hebrew, cities his band has performed in, crucifixes and 17Black, James Bond's lucky gambling number.
Styles is yet to display the ink in public, or reveal his latest addition to fans on his micro-blogging page.
