Ali's rep, Steve Honig, has attributed the teen's changing looks to being in an "awkward phase." "During the past two years, she has gone through a normal teenage growth spurt that has made her taller and slimmer," he said in a statement. "It has also slightly changed the composure of her face, all of which is typical of what happens to kids in their mid to late teens. It's what most people refer to as the awkward stage. Ali is growing up, that's all." Growing... or shrinking?
