Tattoos are losing the stigma that used to be attached to them, and now, it seems like almost everyone we know has at least one. Even those in Hollywood, as more and more celebrities are showing off their ink on social media and on red carpets. Scarlett Johansson, who has been building her collection of tattoos for some time now, just confirmed that the tattoo we all spotted back in August is real by showing it off at the Avengers: Infinity War premiere in Los Angeles.Months ago, eagle-eyed fans noticed Johansson sporting a large back tattoo in a black-and-white floral design, but it was unclear whether the ink was real or for a role. Now it seems we have our answer: The tattoo is here to stay.The tattoo was mostly visible peeking out from a silver strapless dress at the Avengers: Infinity War premiere, which Johansson attended with her partner, Colin Jost. In pictures from the event, it appears that the flowers are roses on a vine, and given that her daughter is named Rose, the tattoo seems especially sweet.
