Katy Perry is so down to earth and just to prove it she took the New York City Subway on New Years Eve to attend a party for friend Rita Ora. The New Years Eve party was held at The Standard in NYC. Katy Perry rode the A train and captioned her photo, ““A train squad game strong.” She wore a beige suit, a black dress and jeans while riding the A train to Rita Ora’s black-tie affair. But katy Perry later changed into a beautiful sequin dress. Check out the pics in the gallery..
