Best Celebrity Style April 2, 2012

Thanks to a week of ultrachic frocks, denim combos, and a little leather, we're feeling newly inspired for Spring. The latest round of celebrity looks offers both the glamour we love — like Kate Bosworth in the prettiest Prada frock — and more casual takes to mimic in our own day to day. We spotted Rosie Huntington-Whiteley giving us a seasonal approach to leather in Theyskens' Theory and Olivia Palermo supplying a way to style up your sequins right now. Inside there's more from our favorites — Jennifer Lopez stunned on American Idol, and Beyoncé and sis Solange both gave us looks to love. Click on for our top 10.
