URGENT ¥¥¥ Jennifer Lawrence wins best actress Oscar

Jennifer Lawrence won the Oscar for best actress at the 85th Academy Awards on Sunday for her performance as a headstrong young widow in "Silver Linings Playbook."

"This is nuts," quipped Lawrence -- who got a sympathetic standing ovation after she tripped on her way up onto the stage in a Dior Couture gown -- as she gripped the first Oscar of her career.
