Nicole Kidman in glamorous look London - Arabstoday Nicole Kidman was guest of honour at the private opening of Omega House, during the 2012 Summer Olympics at the House of St. Barnabas in London, England, and she was dressed to impress. The star, who is a brand ambassador for the Swiss company, looked stunning in a beautiful sleeveless Azzedine Alaia black dress with black lace up sandals. Her hair was styled in soft waves and she sported minimal make-up. Clearly thrilled at the experience, the 45-year-old big screen star posted a picture of herself at the event with a caption reading, \"At the Olympics with omega! Amazing! Wow”.  It was a return to the spotlight for the star who has tried to stay out of the public eye to avoid getting involved in the divorce drama unfurling between Tom Cruise and Katy Holmes.
