Naomi Watts made a stunning transformation.

The Australian actress stopped the press at the People’s Choice Awards on Wednesday night with her glamorous turn on the red carpet.

Naomi was a breathtaking blend of sexiness and elegance in her Alexander McQueen ensemble which featured a backless gold top with gem encrusted collar and her floor-length trailing black skirt.

Wearing her golden-blonde hair half up, half brushing the side of her cheek, the 44-year-old actress brought a big dose of movie star glamour to the Nokia Theatre in Los Angeles.

Naomi, who stars in the film The Impossible about a family torn apart in the aftermath of a devastating tsunami, wore a light dusting of make-up to accentuate her delicate features.

Her jewelry by Jennifer Meyer was minimal as well, with fragile gold earrings dangling from her ears and slim bracelets gracing both of her wrists.

She carried with her a Jimmy Choo bag that matched her Jimmy Choo heels.

Being an A-lister, Naomi probably had a little help from a professional stylist, but she was the one who wore it all so well.

Naomi’s glossy star presence was quite a contrast to how she looked just the day before.
