The seven-time Grammy winner displayed her ink on Wednesday in what appears to be its raw state ― the size and design had fans buzzing.
“Back tatt so fye,” one wrote. “It looks absolutely killer,” another praised.
Eilish had offered a peek of the tattoo previously but, this time, gave followers a full look, though it seemed to be a work in progress when the photo was taken.
People noted she also has a dragon tattoo on her thigh, fairies on her hand and her name on her chest.
