Jessica Alba Sparkles with Swarovksi for the Holidays

Jessica Alba sparkles in Swarovski.

Jessica Alba and Swarovski Elements are celebrating the holidays with plenty of sparkle. The actress hosted a private dinner last night to fête Swarovski Elements’ and Rodeo Drive’s first holiday celebration.

Stylists, editors and members of the Beverly Hills community gathered at Soho House West Hollywood for a cocktail party and dinner. Alba wore a Swarovski Crystallized Winter Garden necklace in honor of the occasion - and for a cause. The actress has teamed up with Swarovski Elements and the City of Beverly Hills to celebrate the holidays and support Baby2Baby, a local charity which provides essential items to families in need.

On Nov. 21 Alba will host the Rodeo Drive Holiday Lighting Ceremony to unveil a state-of-the-art crystalline installation sparkling with thousands of Swarovksi Elements and LED lights. Innovative technology will create an interactive holiday experience when messages tweeted from around the globe using the hashtag #letitsparkle appear on the sculpture's electronic screens.
