Ireland Baldwin loves making “impulsive decisions”: like getting a spontaneous butt tattoo. The 25-year-old model revealed this new tattoo in an Instagram photo on April 19, which was taken at the beach. It showed Ireland rocking a sugary sweet purple and pink bikini and with her back turned to the camera, so that you could see her new ink that read “Yeehaw!” over a cowboy boot over her derriere. Quirky and sexy!
