"I'm so excited to march with these two incredible ladies tomorrow! ?," Grande captioned a sweet snap 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! ??."
Though the pop star didn't reveal whether she would be marching in Washington, D.C. or one of the other marches across America, she's definitely enjoying spending a little quality time with her family.
"Three grandes to go please," she wrote alongside a cute shot of herself cuddled up to Joan and Marjorie.
Grande definitely supports the message of the Women's March on Washington, which will raise awareness to support women, minorities and the LGBTQ community throughout Trump's administration.
Last month, the "Dangerous Woman" singer spoke out about feeling "sick and objectified" after a run-in with a misogynistic fan who called her "sexy as hell," 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, adding that these are the "kinds of moments that contribute to women's sense of fear and inadequacy." "I'm an adult human being in a relationship with a man who treats me with love and respect."
