It’s Keith Urban’s Tattoo!
Keith Urban has a number of tattoos, four of which are visible if you look closely at this picture. There's the thunderbird on his left forearm, two on his right arm (one reads "Love Conquers All"), and a phoenix emerging from behind his black shirt. There is also one of an eagle on his right shoulder that Urban says he gifted himself when he turned 24-years-old. The others are for Nicole Kidman's eyes only.
