Jessie J Sports Purple Hair at Blackberry Event in London

Jessie J is taking a cue from hair dye queens Katy Perry and Lady Gaga, as the British songstress has changed her jet-black locks to a vibrant shade of purple. At a Blackberry event in London, England on Sept. 20, Jessie J showed off her new electric-colored locks on the red carpet. Later that evening, she performed for the masses gathered at the launch party for BBM Music and the Blackberry 7 Smartphone Collection.

Jessie J hit the red carpet wearing a red shirt dress and two-toned black leggings. Her footwear consisted of one blinged-out metallic gold shoe and a gold bejewled boot, which Jessie has been wearing for months now as she heals from a broken foot. She also performed upon a red and gold couch at the event, wearing a purple and green cosmic-printed leotard to match her new purple locks.

Before the show, she spoke to Gigwise about the surgery that followed the break, saying, "When I came around from my anaesthetic, my doctor said that the inside of my foot was like a Crunchie bar. They had to take all of it out, and had to put somebody else's bone in and they put a little plate on the other foot with four bolts so it is pretty sore." Although that image is quite graphic, it shows the gravity of Jessie's injury.
