One reason we love Lena Dunham? She's comfortable in her own skin, and her latest Instagram post proves that notion once again.

The Girls star took to the social media platform to share a video of herself dancing that was taken by none other than her musician boyfriend, Jack Antonoff. In the clip, she wears a blush pink American Apparel bodysuit ($36, and holds her hands on her hips as she shakes back and forth while looking away from the camera. "Too proud of my moves not to share this special GIF @jackantonoff made," Dunham captioned the hilarious post. Check it out below.
