It’s been nearly a month since hundreds of Nigerian schoolgirls were kidnapped by the terrorist group Boko Haram, and now celebrities are using their star power to help raise awareness of these women’s plight — and, hopefully, to help get them back home.

With the hashtag #BringBackOurGirls, notable figures such as Michelle Obama, Reese Witherspoon, and Jessica Biel are using social media to spread the word and offer support for the girls and their families. 

“Heartbreaking! Let’s all raise awareness! #BringBackOurGirls” Kim Kardashian captioned this image.

Other celebs used Twitter to get out the message:

I’ve never wished I was actually NIKITA- till these girls went missing in Nigeria. So frustrating and heartbroken #BringBackOurGirls
