The singer was seen showing off some incredibly awkward/hilariously awesome moves at The Weinstein Company and Netflix's Golden Globes After-Party on Sunday night -- getting wild to Rihanna's "Umbrella" and Def Leppard's "Pour Some Sugar On Me."
Swifty was hanging out with BFFs Sarah Hyland, Jaime King and Hailee Steinfeld all night, singing and shaking it in her knit Julien MacDonald LBD.
It looks like she was having a blast -- and we love seeing her try to dance sexy, it's cute.
What do you think of her moves?
