Watch Out For A 'Badass' Cameo In Demi Lovato's 'Really Don't Care' Video

Demi gives us one more tease of her video before it premieres tonight at 5 p.m. ET

Today is the day you've been waiting for Lovatics, because Demi Lovato is just few hours away from world premiering her brand new video, "Really Don't Care."

Today at 5 p.m. ET. on MTV, MTV Hits, and LOGO, we will see Demi take over Los Angeles’ Gay Pride Parade, celebrating with the crowd and sending a clear message to all the haters with her powerful pop-anthem.

"When we performed that at pride there were protesters that were saying that being gay was a sin and stuff like that," Demi, who was the Grand Marshall, told MTV News of what it was like shooting at the parade on June 8. "And it felt amazing to sing with other people in their faces and sing "I really don't care."

Demi has been teasing us over the past few days with clips from the video, but she's not done yet, telling us to keep on the lookout for a special cameo.

"I have a special guest at the end of the video and its just such a badass moment that I'm so excited for my fans to see," Demi said, telling us that it is not a fellow singer. "It's just so cool."

"Really Don't Care" is the fourth single off her album Demi. At the time of it's release, the pop star considered this to be a song about a break-up, but after thinking more about the song she wanted it to have "a deeper message" since she stands for much more than that.

"One of my good friends who is gay, we were talking about this and he said 'you know what? I would really like to see someone stand up for us. So when I heard that idea I said 'absaf--kinglutley that's amazing' and I love that we were able to turn this song into an empowering anthem rather than just another negative break-up song," Demi said. "It goes for not just people in the LGBT community, but for anyone that's been bullied."

Fans can see Demi tonight on Logo's TV inaugural "Trailblazers" special where she revealed and paid tribute to her grandfather who was a trailblazer in his own right in the LGBT community, coming out in the 1960s.

You can watch it all on Logo TV at 9p ET.
