We've become accustomed to pictures of Katy Perry on stage dressed as a cupcake and sporting a blue wig so we're delighted she's gone for something different to keep our attention.
Katy stepped out to do some shopping in Mayfair this weekend in a sheer swan print dress, sunnies and black boots. The darker colours make this outfit a total contrast to the lilac bodycon dress she wore for her perfume launch.
What do you think of her serious-swan style? Leave us a comment and let us know if Katy is leaving you hot or cold. Take a look through some of Katy's best fashion moments below.
