Sky Ferreira Performs One, Talks Tattoos

Sky Ferreira may sing catchy pop songs, but this 18-year-old singer/songwriter is not your average cookie cutter pop star. In a new interview with MTV, Sky reveals she has a tough side while talking about her many tattoos, including a large sword on her forearm and a tear drop on her finger that she got to commemorate rapper Lil Wayne going to prison.

Sky also recently recorded a video of herself singing "One" in Cologne, Germany. It's the first time that she ever sang acoustic in front of an audience and now all of her fans can check it out. "One" was co-written by Sky in just 30 minutes and produced by Bloodshy & Avant (Madonna, Britney Spears, Kylie Minogue). The song will be on her forthcoming debut album, along with her current single "Obsession," due out next year.
