Our best dressed stars of the week had very different looks.

Mila Kunis was stunning in a chic Chacarel mini with floral pattern. Rachel Bilson also went the floral route with an Erdem blouse and bright red pants. Olivia Wilde dazzled in red herself -- a fiery Antonio Berardi dress. All three had summery streaks in their hair.

Jessica Alba, Ashley Tisdale and many more also made the cut. Click on the "Launch Gallery" button below to see all the looks.
