Imagine Dragons lead singer Dan Reynolds showed his support for the LGBT community by waving a rainbow flag at the Lollapalooza Brazil Festival in Sao Paulo.

Reynolds, 30, documented the moment with a special Twitter post.

“Celebrate our diversity. embrace our LGBTQ youth. to ‘accept’ does not simply mean to ‘love’ – it means you give true validity and fully embrace and support diverse sexual orientations and do not see ones sexuality as ‘incorrect’ or ‘sinful.’ love is an empty word otherwise,” Reynolds tweeted.

Reynolds was raised Mormon and previously taught that homosexuality is a sin. Last year, he apologized to the LGBT community in his acceptance speech for the Trevor Project’s Hero award.

“I knocked on thousands of doors. For those two years when people asked me what the doctrine was and they said, ‘Hey, I’m gay,’ I thought that it was a sin because that’s what I had been raised to teach,” Reynolds said at the time. “I hold regret about that until this day. I wish I could re-knock on those doors and tell them I was wrong. I can’t do that. All I can do is come forward to you today and say I’m sincerely sorry.”

He will also appear in the documentary “Believer,” which will chronicle he and gay Neon Trees lead singer Tyler Glenn as they advocate for LGBT Mormons. The documentary received a standing ovation during its screening at the Sundance Film Festival.

It premieres on HBO this summer.
