Demi Lovato is never shy to stand up for what she believes in, and this time it is for the LGBT community. Earlier this month she led the LA Pride parade as grand marshall, and is headlining the NYC Pride's Dance on the Pier in Tribeca on June 29.

"I've never spoken about this before, but my grandfather was a trailblazer himself," she explained at Logo TV's Trailblazers event Tuesday.

"He was brave enough to come out in the 1960s, and I feel that a lot of my spirit has come from him. He passed away a few years later and I only wish he could have been able to see all the progress that has been made. It's such an honor to be welcomed and embraced by the LGBT community, so thank you very much," the songstress continued.

Lovato also played Santana's (Naya Rivera) lesbian love interest on season five of "Glee."

Others involved in the special include Daniel Radcliffe, Adam Levine, Nate Ruess, Lance Bass, Joe Manganiello, the cast of Orange Is The New Black and Sia.

The former Disney star recently opened up to Seventeen about positivity and giving back.

"I like to have friends in my life who believe they're going places and are working toward their dreams. When you're growing and the people around you aren't, that's when you have to start shedding them," Lovato stated.

 I've done that a lot over the past few years, but it has been so worth it, because the people in my life today inspire me to keep being creative, to have fun, and to be a good person."

"When I give back, I don't question my self-worth. I know that if my career were to fall apart tomorrow -- even if I were to never have money or fame again -- I'd still have value in my soul, because I know that I can have an effect on someone else's life," she then added.
