Taylor Swift Filmed Lena Dunham’s Dance Moves As The 'Girls' Creator Rocked Out To Her Namesake Rap Song — VIDEO

It's been a rough week, you guys. There's a lot of crap going on in the world. Sometimes during a week like this all you can really do, if you've got the privilege to do so, is put on some music and freaking dance it out. Add the glittering celebrity presences of Taylor Swift and Lena Dunham? That's a mightily cathartic opportunity right there.

The pop star and the Girls creator and star danced it out Wednesday, posting a small tidbit of it to the former's Instagram. The catalyst to the dance party in this case appears to have been the song "Lena Dunham" by Hand Job Academy. As Swift's Instagram caption reads:

This was what happened when Lena and I found out that there is a rap song called "Lena Dunham."

I mean, how would you react if there were a rap song about you? The first order of business would obviously be to dance it out.

The most notable part comes right at the end, and if you blink or mute it for just one smidge of a second, you'll miss it. It's that "Yasssss" Swift busts out that's so awesome. These are definitely two ladies who rock out in Oregon Trail cosplay from time to time.
