Katy also typed out a message, saying, 'Lost in Tokyo. Counted down with strangers on a sidewalk... all is as it should be.'

She signed off by saying, 'To a better New Year,' perhaps a nod to the fact her candidate Hillary Clinton, who she promoted and performed for, somehow lost to rank outsider Donald Trump in the US presidential election.
