Don’t mess with Demi.

Demi Lovato dropped the music video for her latest single, “Really Don’t Care,” on Thursday.

In the video, the LGBT advocate takes on anti-gay protesters at L.A. Pride in West Hollywood earlier this week.

Her only words for the haters: “I really don’t care.” She gets a little help from the rest of the crowd – which includes blogger Perez Hilton, "Vampire Diaries" star Kat Graham and Travis Barker – during the event, in which she performs through the streets on a float.

She also has an assist from Cher Lloyd, who raps on the track. Demi, who appears on Logo’s first annual Trailblazers special, revealed this week that the issue is close to her heart in part because her grandfather was gay.

“I’ve never spoken about this before, but my grandfather was a trailblazer himself,” she said (via “People”). “He was brave enough to come out in the 1960s, and I feel a lot of my spirit has come from him.”

You can watch “Trailblazers” Thursday at 9pm on Logo, and check out Demi’s new video above!
