Gal Gadot is speaking up against teenage marriage.

The actress, 35, joined her “Wonder Woman” co-star, Robin Wright, in the Instagram campaign, #VowForGirls, raising awareness of the millions of teenage girls who are being forced into marriage.

“Thank you @robingwright for nominating me and shedding light on this important cause and this organization @vowforgirls,” she captioned a selfie. “It’s 2020 and millions of young girls are still being forced into teenage marriages across the world – this needs to stop! Girls in this era must have the right to choose who and when they marry, they must have the freedom to choose their own path.”
