When you're ringing in the New Year at New York's The Standard, you know you're going to have a classy night. So how did Katy Perry show up to the exclusive party? On the subway, of course. Maybe all the limos were rented out or something...

Yes, Katy ventured underground with her good-looking friends to take the A train to the December 31 party, where she would later hang out with Rita Ora.

Although the NYC subway system involves a lot of anonymity, it would be hard to miss Katy and her crew, dressed in bulky fur coats and posing for a giant group photo -- all while exuding celebrity confidence.
