This week was all about colorful gowns. And the winners are...

Rihanna in Christian Dior at the 2011 BRIT Awards. Rihanna popped in this multipatterned, multitextured, multicolored masterpiece, which she further amped up with matching teal pumps.

Heidi Klum in Julien MacDonald at the 2011 Grammy Awards. The "Project Runway" star exuded old Hollywood glam from head to toe in this gleaming, gold gown, which boasted sexy cutouts along the shoulders and in back.

Thandie Newton in Monique Lhuillier at the 2011 BAFTA Awards. The actress oozed romance in this rosette-print, paint splashed taffeta gown, which she paired with modest jewelry and a chic chignon.

Jessica Alba in Atelier Versace at the 2011 BAFTA Awards. Jessica looked the part of a tribal princess in this royal blue gown with intricate ruching along the corset-like bodice. I also love the actress's exotic necklace and ring pairing.

Nicole Kidman in Jean Paul Gaultier at the 2011 Grammy Awards. I'm not exactly Nicole's biggest fan when it comes to the red-carpet, but even I can't deny that she looked gorgeous in this gardenesque gown, which concluded with a partially-sheer and ruffled fishtail train.
