Nicole and Keith Duet at G’Day USA Ball

Nicole Kidman and Keith Urban stole the show at the G’Day USA Ball on Saturday night in Los Angeles by serenading mate Simon Baker. Nicole has always insisted that she would “never” duet with her famous hubby, but obviously made an exception. Simon was receiving an award at the event and the pair sang Men at Work’s "Land Down Under" and changed the lyrics to “And his name is Simon Baker, surfer dude, home renovator.” One of Nicole’s best friends is Simon’s wife, Rebecca Rigg.

Also making appearances at the event were Toni Collette, Sam Worthington, Olivia Newton-John, Mia Wasikowska, Jennifer Hawkins, Cameron Diaz, John Travolta, Holly Valance and a newly divorced Greg Norman. One surprise no-show was Chris and Liam Hemsworth. The boys had rsvp-d for the event and Liam was expected to make an appearance with girlfriend Miley Cyrus, but unfortunately they were nowhere to be found. Now we just have to wait for the Keith and Nicole duet to hit You Tube.
