Demi Lovato has become something of an LGBT activist and tonight she revealed why. On a Logo TV special, the singer revealed her grandfather was gay. “I’ve never spoken about this before, but my grandfather was a trailblazer himself. He was brave enough to come out in the 1960s, and I feel a lot of my spirit has come from him.” She continued: “He passed away a few years later, and I only wish he could have seen all the progress that has been made, it’s such an honor to be welcomed and embraced by the LGBT community.”
