Demi Lovato used her American Music Awards platform on Sunday night to sound off on bullying and bodyshaming.

The singer, who began her performance while sitting in the audience and watching a slew of mean tweets flash onscreen, told viewers: “There’s so much hate in this world…We have to rise about and never say sorry for who you are.”

What followed was an unapologetic performance of her hit “Sorry Not Sorry” that drew singalongs from BTS and Rachel Platten.

Lovato also showed her support for bullying victims by bringing special guest Danica Roem, Virginia’s first transgender legislator, along with her to the show. The move is part of GLAAD’s Together movement, which promotes the unification of marginalized communities.

“Demi Lovato and Danica Roem are two strong and inspirational women who embody the need for all Americans to stand together united and to take action today against any form of discrimination and oppression,” said GLAAD President and CEO Sarah Kate Ellis.

Following Lovato’s performance, Roem turned to Twitter to thank the singer for the opportunity. “Thank you for the once-in-a-lifetime opportunity @ddlovato,” Roem wrote.
