Tearful Oscar-nominee Keira Knightley was comforted by Sienna Miller just hours before the Academy Awards ceremony yesterday (05MAR06), after the pressure became too much for the 20-year-old star. Knightley, who has been nominated in the Best Actress category for her turn as ELIZABETH BENNET in PRIDE + PREJUDICE, became so overwhelmed by photographers and fans, she fled LA restaurant The Ivy to meet up with Miller at the Chateau Marmont hotel. And the blonde star did a good job of cheering her chum - just hours later Knightley was all smiles, gracing the red carpet in a glamorous Vera Wang creation. Knightley previously expressed her Academy Award horror, she said, "You get trotted out like as Britain's prize poodle and they give you marks out of 10 for what you are wearing and what your jewels are like. "It's a bit scary."
