Best Looks of the Week: Jessica Biel and Kate Hudson Dazzle in Beautiful Blues

The stars brought out their best Tiffany & Co. bling for the iconic jeweler's Blue Book Ball this week. And while we loved the sparkling diamond currant brooch Jessica Biel pinned to her hair, and the hard-to-miss pear-shaped diamond-and-morganite earrings Kate Hudson wore for the glam event, the leading ladies' gowns weren't too shabby either!
Biel dazzled in a fab floral Elie Saab gown in navy, while Hudson opted for an oh-so-appropriate Reem Acra gown in (you guessed it!) Tiffany blue. 

Red carpet regular Gwyneth Paltrow was also in attendance in a sleek Ralph Lauren dress, but we were more impressed by the Goop gal's gutsy decision to wear an Erdem pant-and-shirt pairing in a punchy floral print to the Iron Man 3 premiere in Paris. The stylish springtime look made the star look as fresh as a, well, flower in the City of Lights.


And speaking of fresh, Selena Gomez's printed Etro dress helped her pop on during her appearance on The Ellen Degeneres Show. Meanwhile, Olivia Wilde opted for a little black A.L.C dress with sexy sheer paneling, proving a gal can't go wrong with a classic LBD no matter what the season!
