The Hadid sisters proved they're more than just pretty faces when they joined a protest against Trump's controversial Muslim ban.

The girls took to the streets in New York to denounce Trump's ban on residents of seven Muslim countries entering America.

The Hadid family have close ties with the Muslim community as their dad Mohamed Hadid is Muslim, as is Gigi's boyfriend Zayn Malik. 

A photo from the protest showed Gigi and Bella proudly holding a sign which read: "We are all Hindus, Buddhists, Muslims, Atheists, Christians, Jews."

The supermodel sisters joined a large crowd in Battery Park, shouting: "No hate, no fear, immigrants are welcome here."

And it seems like they aren't the only ones with strong feelings on the subject.

Fellow model Cara Delevinge echoed their sentiments as she posted the following photo from a protest to her Instagram account.

We're glad to see Gigi and Bella are using their influence to stand up for others and defying stereotypes about models while they're at it!
