In an interview with MTV, the Twilight star gamely discusses the evolution of his scene-stealing locks, ranging from the so-called "Wavy Forest" and "The Cullen Pouf" to the "Windswept What the F---" and "Controlled Chaos." He admits that he's partial to the "forest thing" and even recalls walking the red carpet for Harry Potter and the Order of the Phoenix in 2007.
