Singer Demi Lovato revealed on Wednesday they identify as nonbinary and are changing their pronouns, telling fans the decision came after “self-reflective work.”

“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,” Lovato announced on Twitter and in an accompanying video, adding they will “officially be changing my pronouns to they/them moving forward.”

Lovato said they picked gender-neutral pronouns as “this best represents the fluidity I feel in my gender expression.” They added, “I’m doing this for those out there that haven’t been able to share who they truly are with their loved ones.”

Anthony Allen Ramos of GLAAD said nonbinary people live outside the categories of male or female and should be respected for who they are.
