A rep for the 23-year-old "Don't Wake Me Up" singer subsequently denied that the fresh ink was a rendering of either Rihanna, 24, or any battered female.
"I'm an artist and this is art. Dia de los Muertos," Brown Tweeted Tuesday night, referencing the Mexican Day of the Dead, held Nov. 1; the new stamp is instead a sugar skull, an image associated with the celebration. The image was also inspired by "a MAC cosmetics design he saw," his rep told TMZ.
