Demi Lovato put her support for the transgender community of North Carolina front and center during her Billboard Music Awards performance on Sunday night (May 22nd). The singer took to the stage to perform her hit ‘Cool For The Summer’ while wearing a t-shit featuring a gender inclusive bathroom symbol, in response to the discriminatory HB2 law.

The HB2 law, which was passed in North Carolina at the end of March, blocks local governments from passing anti-discrimination rules to grant protections to gay and transgender people. The law also dictates that transgender people must use public bathrooms corresponding to the gender on their birth certificates.

In a press release GLAAD President & CEO Sarah Kate Ellis praised Lovato, who has previously won GLAAD's Vanguard Award, for showing her support for the transgender community. “Demi Lovato continues to be a fearless ally for LGBT equality and acceptance,” Ellis said.

“By wearing her support for the transgender community, Lovato is raising critical visibility for vulnerable LGBT North Carolinians and sending an invaluable message of support to transgender people everywhere.”

Lovato will also be selling a replica of the t-shirt during her upcoming tour, with all proceeds going to LGBT organisations in North Carolina. The proceeds will benefit Equality NC, the state organization working to secure equal rights and justice for LGBT North Carolinians, as well as Time Out Youth, a Charlotte-based community center that provides support and services for LGBT youth, GLAAD announced.

This isn't the first time Lovato has taken a stand against the ‘bathroom bill’. In April she and Nick Jonas announced they’d be cancelling their upcoming shows in North Carolina to protest the law.

“After much thought and deliberation, we have decided to cancel our Honda Civic Tour: Future Now shows in Raleigh and Charlotte," read a note signed by both Lovato and Jonas on twitter.

"One of our goals for the tour has always been to create an atmosphere where every single attendee feels equal, included, and accepted for who they are. North Carolina’s discriminatory HB2 law is extremely disappointing, and it takes away some of the LGBT community’s most basic rights and protections."

“But we will not allow this to stop us from continuing to make progress for equality and acceptance. We know the cancellation of these shows is disappointing to our fans, but we trust that you will stand united with us against this hateful law.”
