Naomi Watts was maid of honour at her film publicist friend Emma Cooper's recent wedding in Australia.

According to The Australian Daily Telegraph, the '21 Grams' star wore a white lace dress to the ceremony at Sydney's Shore Chapel at which her partner, 'Scream' star Liev Schreiber gave a reading.

Schreiber spent the rest of the ceremony entertaining his and Watt's sons, Sasha, three, and two-year-old Samuel.

Cooper, who married Australian television writer Henry Cripps, has been a film publicist for 20 years and has befriended a lot of stars during her career, several of whom flew in from Los Angeles especially for yesterday's wedding.

The 'Mentalist' star Simon Baker was there with his wife Rebecca Rigg, as well as 'Without A Trace' star Anthony La Paglia and his wife Gia Carides and Australian film director Gregor Jordan.

Watt's brother Ben was the official wedding photographer and she is godmother to the newly weds son Casper plus they are all neighbours in New York.
