Hilary Duff  is released her new single, "Chasing the Sun ," this week and it got us thinking of how much we loved her back in the day. Before she was a sweet mother to her son, Luca , she was a — sometimes literally — animated teenager on Lizzie McGuire with the coolest friends and a sassy personality . Hilary was one of the early-'00s It girls, not only starring in her own TV show and movie but also romancing Chad Michael Murray in A Cinderella Story and both Aaron Carter and Joel Madden  in real life. We're coming clean about our total girl crush.
