Kate Hudson and Goldie Horn wore matching dresses to the Elle Women in Hollywood gala on Monday (18.10.10).

The 'Nine' actress and her Hollywood legend mother accidentally attended the event in the same style one-shoulder dress, with Kate sporting one in black with iridescent paillettes by up-and-coming designer Prabal Gurung, and Goldie in a white Gianfranco Ferre design.

Kate said: "When we came in we were like, 'Ooh,' and we felt, like, a one-shoulder thing happening!"

Goldie later presented Kate with one of the night's awards at the gala, hosted by Harrison Ford.

Both Goldie, 64, and Kate, 31, laughed off their dress clash, but Kate admitted the harshest critic of her dress sense is her son Ryder.

She added: "Oh my gosh, he's my biggest critic, always asking: 'What is that?' I always know when he likes it when he sees me and he doesn't Say Anything and he gets kind of flushed. I go, 'Uh-oh. That means you like it!'"
