Lena Dunham and Jemima Kirke are crazy for Miley Cyrus' "We Can't Stop," and are showing the world their love for the controversial new music video.

On Thursday, Lena posted an Instagram video of her spanking Jemima with a spatula-like object while Jemima is singing Miley's super catchy song. But you can barely hear Jemima over Lena's constant laughter. The two really seem like they're having a good time, but are they actually fans of the song or are they poking fun at Miley's craziness?

I guess we'll have to wait until the new season of Girls to see if Lena adds in some montages of the girls twerking and sticking their tongues out for no apparent reason. But until then, fans can just watch this Instagram video over and over, we know we will.

Check out the girls getting silly below.
