We don't call Demi Lovato the #1 LGBT ally for nothing!
The 21-year-old "Really Don't Care" singer has teamed up with the Human Rights Campaign to produce a video in support of gay marriage.
"I believe that love comes in all different shapes, sizes, and colors," Lovato says. "So whether you're LGBT or straight, your love is valid, beautiful, and an incredible gift."
The beautiful starlet served as the Grand Marshal of this year's Los Angeles Pride Parade, and recently revealed that her own grandfather was gay.
