Australian glamour mingled with Swiss elegance on Saturday in London, as Nicole Kidman
helped launch Omega House on behalf of the watchmaker, an opening timed to the Olympic Games
Kidman, 45, and her husband Keith Urban
, 44, were the guests of honor at a soiree held by Omega, the official timekeepers for the London 2012.
The couple braved a crowd of enthusiastic fans to get into the building, but later looked relaxed and held hands as they mingled with around 400 guests in the garden, including actors Eddie Redmayne
of My Week with Marilyn
and Kit Harington
of Game of Thrones
They also watched some Olympic swimming action, and their timing was perfect, as Kidman beamed when Team Australia won the gold in the women's 4x100 relay.
Kidman, wearing a long black dress by Azzedine Alaia and Manolo Blahnik heels, is an ambassador for the Omega brand.
She and Urban also attended the opening ceremony
