U.S pop sensation Katy Perry has arrived at London’s famous department store, Selfridges, to unveil her debut fragrance.  

The ‘California Gurls’ singer who is newly married to Russell Brand is releasing her first ever perfume this afternoon (November 12), which is called ‘Purr’.

Perry, 25, who often tweets photos of her cat, Kitty Purry, along with intricate nail art showing the feline’s face, just tweeted:

“Is @SELFRIDGES in LONDON!!!”

The bottle, which is a deep purple colour, is in the shape of an elegant cat complete with diamond eyes and a heart-shaped collar charm, and is available in two sizes from today onwards.
