Taylor Swift Throws Wild VMA Nomination Party

Taylor Swift let her hair down, and then ferociously moved it sideways, in what looks like a celebration that was fueled with a little drinky drinky.

Taylor threw a party to celebrate not 1, not 2 but 10 VMA noms, which include Video of The Year and Song of The Year for her singles, "Me!" and "You Need to Calm Down."

Calming down was on no one's mind Saturday night at Beauty & Essex in L.A., when Taylor busted moves with some pretty impressive backup, including Laverne Cox, Chester Lockhart, the HAIM sisters and Justin Mikita.

BTW ... she'll perform at the VMAs on the 26th ... and it'll be the first time in 4 years.
