Miley Cyrus has been announced as the headliner for the Capital Pride Concert in D.C. on June 11. The show, launching at 1pm on Pennsylvania Avenue, will also feature performances by Tinashe, The Pointer Sisters, and Vassy.

Cyrus has been an outspoken ally in recent years, speaking out about marriage equality, LGBT homeless youth and other issues, and founding her Happy Hippie Foundation.

“We are unapologetically proud to join with Miley Cyrus, Tinashe, and all of the headliners at the 2017 Capital Pride Festival! This is sure to be an awesome weekend full of great music and lots of fun,” said Tommy Chuck, program director for Hot 99.5, which is sponsoring the concert.

The Equality March, an LGBT rights demonstration, is slated for the same day.

“We are working in conjunction with the Capital Pride Alliance to incorporate the March into the 2017 Celebration of Pride in the Nation’s Capital,” wrote organizer David Bruinooge on Facebook. “We want to build off the momentum the strong women in the US and around the world started on January 21st. They set the tone with their leadership and it is our intention as a community to follow their lead and play our part. This will be an ALL-inclusive and peaceful event.”

He’s hoping organizers will incorporate the Pride march into existing events around the world.
