Nicole Kidman: 'I'm highly strung'

Nicole Kidman has revealed that she has difficulty keeping her cool when she becomes upset.

The star, who recently gave birth to daughter Sunday Rose, commented that she "can't hide it" when something annoys her.

"I would have to describe myself as emotional and highly strung... If something upsets me, it really upsets me. If something makes me angry I get really angry," The Sun quotes her as saying.

However, Kidman added that she would like to think that she is loyal and a fun person to be around.

The actress and husband Keith Urban were recently spotted at a football match in London.

Onlookers saw the pair at the clash between Chelsea and Manchester United at Stamford Bridge, which ended 1-1.
