Katy Perry in pink
Katy Perry pink beehive
Pop princess Katy Perry celebrated her stunning X Factor performance by taking hubby Russell Brand's parents out for a night in London town - styling it up in an eye-popping all-pink ensemble.
Not content to simply blend in with the crowd, Katy wore her cute bubblegum tresses in a 60s inspired beehive, matched to a wow-worthy fluro fuchsia Giambattista Valli dress.
The singer treated her inlaws to dinner at Nobu Berkeley after watching Ghost the musical at the Piccadilly Theatre.
