There's nothing more feminist than using Twitter to call out sexism with your mother. That's what Ariana Grande and her own mom, Joan, did on Sunday, beginning when the latter tweeted this: The discrepancies are obvious: "Women's interests" magazines are devoted to beauty, fitness and celebrity culture. "Men's interests" feature diverse covers and subject matter. With several celebrities and prominent women in Hollywood speaking about their feminist views, it's extra empowering to see Grande and her mother team up to call out sexism in the media. As Joan put it, "It's 2015, this must stop, awareness is the only way."
