DAMN GURL, werk that piano!
The Fancy singer was accompanied by Rostam Batmanglij of Vampire Weekend on the piano and she definitely used that piano for more than just a musical accompaniment.
She got up on top of it in some HUGE high heels and sang her heart out. We LOVE it!
Not to mention her vocals were totally ON POINT.
Seriously, though! Ch-ch-check out the whole performance (below)!
