Nonbinary Celebrities Pre-2010s for Historical Reference

Are there any celebrities or famous people who came out as nonbinary in the 90s or 2000s? I know of binary people. What about nonbinary? I need references for a story set pre-2010s. As far as I know, it's really a blank prior to the mid 2010s when it comes to openly nonbinary famous people. It was very under the radar and mostly passing as binary.
