Demi Lovato is once again standing up for a cause she believes in.
The singer, who revealed last month that her late grandfather was gay, is featured in a new public service announcement on behalf of the Human Rights Campaign.
In the footage, she makes a strong push for marriage equality across the board.
"I believe that love comes in all different shapes, sizes and colors, so whether you are LGBT or straight, your love is valid, beautiful, and an incredible gift," Lovato says, adding:
"So let’s protect love and strengthen the institution of marriage by allowing loving, caring, and committed same sex couples to legally marry."
Lovato served as the Grand Marshal of the L.A. Pride Parade last month, performing in front of thousands and giving the finger to haters.
Ever since her rehab stint in 2010, Lovato has been outspoken on a number of issues, from sharing her personal drug experience to telling young women how they should be proud of their bodies.
She also believes in mermaids.
But, hey, no one is perfect.
