Katy Perry is all over Paris Fashion Week.
The newly divorced songstress has been spotted in the front rows at the Yves Saint-Laurent, Chanel and Viktor & Rolf shows, as well as a bevy of parties and exhibits.
Over the weekend, the blue-haired pop star hit up Grandlife's This Is New York event at Le Regine, where she and pals were drinking champagne, "smoking and dancing the night away," a witness told amNewYork.
Meanwhile, Perry's ex-hubby - Russell Brand - reportedly has been partying it up in New York.
