She's pretty bold!

On Thursday, Lena Dunham decided to campaign for women's rights the best way she knew how... by going topless!

The 28-year-old actress posted a picture to her Instagram account showing off her bare chest, with the words "Lena Loves Planned Parenthood" across it.

The half-naked selfie came after a bevy of celebs, from Amy Poehler to Gabrielle Union, joined her online campaign to urge people to vote for women's rights.

She followed it up with a collage of her star support with the caption, "These dream women stand for equality and justice. And they encourage you to vote November 4th."

Looks like she's doing her part!

These dream women stand for equality and justice. And they encourage you to vote November 4th.
