Demi Lovato has told fans that it is okay if they mis-gender them, as long as they have good intentions and try their best.
Those who are non-binary feel as if they do not quite fit into the gender binaries of being a man or woman, and may decide to identify outside the confines of the gender binary.
However, non-binary identities vary and while some people may decide to reject the binary of being a man or woman, others may identify with certain aspects of it.
Writing on Twitter, the 28-year-old said: "I felt the need to post this because I often find that the change in pronouns can be confusing for some, and difficult to remember for others.
"It's all about your intention. It's important to me that you try, but if you make a mistake, it's okay".
They added: "If you mis-gender me – that's okay. I accidently mis-gender myself sometimes! It's a huge transition to change the pronouns I've used for myself my entire life.
