The Women's March just gained a Dangerous Woman.

On Friday, Ariana Grande announced on Instagram that she will join the Women's March today (Saturday, January 21) along with thousands of other women who are participating in order to send a message to Donald Trump—a man who has made misogynist comments and who has been been accused of sexual assault—as well as his administration.

However, Grande won't be going it alone: She'll be joined by her mother, Joan, and her grandmother, Marjorie.

"I'm so excited to march with these two incredible ladies tomorrow!" the pop star captioned a photo of her mom and grandma. "I can't wait to share this #womensmarch with the strongest women in my life and with all of the other strong, beautiful, unique, empowered, brilliant, amazing women out there who are marching as well!"

It's unclear which march Grande will be participating in—whether it's Los Angeles, New York, Washington, D.C. or any of the many others taking place across the country today.

Feminism and women's empowerment are important subjects for Grande, who has been an avid speaker against the objectification of women.

In December, the singer spoke out about a "sick" fan encounter in which a fan was misogynist to her and congratulated her boyfriend, Mac Miller, for "hitting that."

"I am not a piece of meat that a men gets to utilize for his pleasure," she wrote on Twitter. "[These are the] kinds of moments that contribute to women's sense of fear and inadequacy."
