While Katy opted to keep a slight hint of pink in her tresses, the born-blonde singer went back to her roots with the new golden locks. Perry also decided to chop off her longer hairstyle in favor of an edgy bob. Perhaps Katy's best friend Rihanna inspired her new look. After all, Princess Ri showed-off a short, blonde bob just last week on the set of her music video for 'You Da One.'
Joining Katy on the red carpet was hubby Russell Brand -- who was still sporting the same long, brunette shag he's rocked for years. The two put up a united front in the wake of split gossip that haunted them all last week.
What do you think of Katy's new 'do: Tress yes ... or follicle fail?
