Lena Dunham looked super skinny walking the red carpet at a Human Rights Campaign gala in Los Angeles. She's recently lost a ton of weight after making a drastic lifestyle change!

Dunham wore a black halter dress with a red shawl draped around her shoulders.

Her new healthy lifestyle is clearly working, as she looked significantly thinner than she has in the past!

Dunham has changed her diet and started to work out more, saying on Instagram that "exercise has the power to counteract my pain and anxiety."
