She's in love and really doesn't care who knows it! Demi Lovato premiered the video for her latest single "Really Don't Care" on Thursday, June 26, and brought along a special guest—Wilmer Valderrama.

The clip shows the 21-year-old singer at her June 9 performance at the L.A. Gay Pride Parade in West Hollywood, where she served as the Grand Marshal. Riding on a float, Lovato wears an androgynous black leather blazer, a tie and studded pants. She also rocks her shaved-side haircut.

"But even if the stars and moon collide/I never want you back into my life," she sings in the self-empowerment anthem, which features Cher Lloyd. "You can take your words and all your lies/Oh oh oh I really don't care…"

Released just before the end of June Pride Month, the gay-friendly video features two women sharing a kiss, dancing men in short shorts, and Lovato learning a routine from drag queen cheerleaders. Vampire Diaries star Kat Graham and Travis Barker also make cameos.

Most notably, Lovato is accompanied by her on-again, off-again rumored boyfriend Valderrama. In a quick shot, the singer is seen with her arms around the actor as he holds on to her waist. Feigning surprise at getting caught, Lovato and the 34-year-old actor laugh.

Last January, Lovato wished the That 70's Show alum a happy birthday via Twitter. She called him "the funniest, most inspiring, incredible man I know."
