Selena Gomez's latest single, "Bang Bang Bang," is out, and some fans wonder if it was inspired by Justin Bieber. Selena, who dated Nick Jonas from 2008 until 2010, has been getting romantic with Justin for several months. Selena and Justin had a PDA-filled vacation in Hawaii recently and even shared a televised kiss during last month's Billboard Music Awards. Selena's song, from her upcoming album When the Sun Goes Down, is a kiss-off to an ex-boyfriend that has Selena singing the praises of her current guy. In the lyrics, she says he's "a real keeper" and "has more swagger" than her previous significant other. Of course, there are also lyrics that don't apply to Justin, but have a listen and tell us what you think in the comments.
