The fashion crowd loves to party. Like a lot. And besides the ultra-exclusive guest list and equally fabulous party decor, great music is a quintessential part of every news worthy Fashion Week bash.

To that end, it should come as no surprise that the sexy Milan duo known as Dolce & Gabbana tapped the girl-loving Katy Perry to sing her poppy tunes at the designer's showcase they held at their headquarters in Via Broggi last week.

Wearing a sequins number from D&G's spring '09 and clutching a bubble gum pink microphone, the American singer put on a mini concert for a bevy of models, power editors, and socialites. No word if she actually kissed a girl that night, but that's because everyone was probably too busy trying not to catch a cold, or something like that.
