Never heard of Aly and AJ? Well, then you are definitely over the age of 16. Sisters Alyson Renae "Aly" Michalka, left, and Amanda Joy "AJ" Michalka are a pop-music sensation, and now they're giving acting a whirl. Look for Aly in this summer's "Bandslam," which also stars Vanessa Hudgens. Look for AJ in the upcoming film adaptation of "The Lovely Bones." Could one of these two be the next big thing?
