American pop star Demi Lovato is non-binary and has changed their pronouns to they/them, the singer has announced. Lovato, 28, told fans in a string of tweets the decision had come “after a lot of healing & self-reflective work”. They tweeted: “Today is a day I’m so happy to share more of my life with you all – I am proud to let you know that I identify as non-binary & will officially be changing my pronouns to they/them moving forward. “This has come after a lot of healing & self-reflective work. I’m still learning & coming into myself, & I don’t claim to be an expert or a spokesperson. Sharing this with you now opens another level of vulnerability for me.
