Nicole Kidman at the Academy Awards 2017

Never mind the mix-up over the wrong film being announced as best picture.

Nicole Kidman's weird hand clapping is the real talking point of this year's Oscars.

She seemed to be clapping only with the palms of her hand - not her fingers.

Nicole was nominated for best supporting actress for her role in Lion, but lost out to Viola Davis.

She won major fashion points for her champagne-coloured Armani Prive gown.

But it was the hand clap and elongated fingers, shown twice to viewers watching at home, that was most memorable.
