Katy Perry rocks little black dress with blue hair

Hot from her divorce with Russell Brand, Katy Perry continues to mesmerise and allure with her funky looks and fabulous attires. The "One That Got Away" singer looked sexy as she stepped out in London after her show, wearing a sassy little black dress with knee high boots. The dress showed ample curves, and the laces of her boots coordinated with her electric blue hair, and the twenty-seven year old was generous enough to pose with fans  Later on she covered up with a sparkly grey sweater to add glitz and glamour.
