In case you didn’t know, today is Spirit Day, an initiative started by GLAAD in 2010 to stand up against bullying and show support for LGBTQ youth. According to Sarah Kate Ellis, the president and CEO of GLAAD, LGBTQ youth face higher rates of bullying, which is only made worse by social media’s dominating presence in today’s society.

To show solidarity and support, Spirit Day participants are encouraged to either wear purple or “go purple” on their online profiles. Each year many celebrities take part in this movement, and this year was no exception. Check out what some of our favorite celebs did for Spirit Day 2017!

1. Britney Spears

2. Nicole Kidman

This week the #BornPerfect team, GLAAD, and the Trevor Project joined the cast and crew on set for the up-coming conversion therapy movie ‘Boy Erased’ and in honor of that we celebrated #SpiritDay in our support to end LGBTQ bullying. I’m especially proud of my friend, fellow conversion therapy survivor, author of the book, now movie, ‘Boy Erased.’ We couldn’t be more excited for Joel Egerton, Nicole Kidman, Russel Crowe, Luke Hedges and everyone at Focus Features for taking on this powerful story!
