If you tuned in to the MTV VMAs on Sunday night, chances are you're dead because of Beyoncé's 15-minute Lemonade medley. But, for once, we're not here to talk about Beyoncé. At one point during the night, another performance rocked the stage: The Chainsmokers sang their Summer hit "Closer" with Halsey. And, well, we couldn't help but notice how cute lead singer Andrew Taggart is. Born in Portland, ME in 1989, Andrew has been on the scene with fellow bandmate Alex Pall since 2012. While many seem to be speculating about a possible relationship between him and Halsey, neither party has confirmed involvement, so we're going go ahead to assume Andrew's single until we hear otherwise. As such, we've conducted a quick study of his social media accounts and official appearances to quench your thirst.
