Last week we brought you the news that Tulisa dyed her hair blonde, Rihanna's also recently rocked it and now the latest pop star to dye her locks a lighter shade is Alexandra Burke. Opting for a two-tone look, A-Burke went for a orangey-caramel shade and chose to leave her hair down and wavy when spotted out and about shopping at the MCM Store on Sloane Street, London on Friday. We personally much prefer her tresses looking naturally dark, as we also do with Tulisa. What do you think of it heatworlders?
