Demi Lovato is feeling like a "natural woman."

The 24-year-old singer took the stage at the Global Citizen Festival in New York on Saturday, where she didn't just join the organization's fight against poverty, she promoted a cause of her own.

Lovato -- who stepped in after Selena Gomez canceled her appearance due to health issues -- took the time to advocate for gender equality before performing Aretha Franklin's "Natural Woman."

"Thank you global citizens, especially all of you who are working toward the global goal of gender equality and standing up for women and girls everywhere," she said to the crowd. "This next one has inspired and lifted up women everywhere for years, even since before I was born, and it still does."

"This is called 'You Make Me Feel Like a Natural Woman,' and it goes out to all the women and girls," she announced before completely slaying the Franklin hit.

Of course, Lovato couldn't leave without performing few of her own hits, like "Confident" and "Cool for the Summer."

"Natural Woman" isn't the only hit Lovato has covered lately. Earlier this month, the former Disney star killed Adele's "When We Were Young" in concert.
