Here’s why we’ve got to love Katy Perry.

Under normal circumstances, when a star launches a fragrance, the launch photos are very, well…stoic.

But things were quite different when “Purr,” the singer’s newest retail effort debuted at Selfridges in London on Friday.

Katy had a bit of fun with the photogs, wearing a purple frock, which–and I’m sure this is no coincidence–matched perfectly with the fragrance’s packaging.
