Actress Nicole Kidman and her country singer husband Keith Urban cheered on Team Australia on Saturday as the women's swimming team raced to victory in the Olympics relay championships.

The Hollywood stars were the guests of honor at an Olympics party held by Omega watchmakers in London, and they spent the evening mingling with fellow attendees Michelle Williams, Kim Cattrall, Game of Thrones actor Kit Harington and movie producer Harvey Weinstein.

A big screen was erected at the venue to allow sports fans to keep an eye on the London Games, and Kidman and Urban were among those celebrating after watching their home team claim gold in the women's 4x100 relay.
