Actress Naomi Watts keeps her biggest fashion critics close to home - she asks advice from her two young sons.

The Diana actress has revealed she always seeks dress approval from her two boys, Sasha, six, and Kai, four, and they often advise the star on what to wear for movie premieres.

She tells, "When I get ready for a premiere I ask my sons which dress do they like just for fun and they often say, 'No, I don't like that dress'... Kids don't filter. So it's always a good way to get the truth."
