Katie draped a black blazer over her shoulders and rocked a black sleeveless dress with dramatic pleats.
The Logan Lucky actress pulled her long hair into a tight and slick bun. Her smoky eye shadow finished off the dramatic look.
She carried a black leather clutch and gold necklaces dangled around her neck.
This isn’t the first time Katie went out and showed some skin after she and Jamie, 51, called it quits. On August 27 while the actress hailed a cab in New York, she rocked a loose fitting cardigan that came dangerously close into the wardrobe malfunction zone.
Katie and the Baby Driver actor reportedly broke up in August, when Jamie was seen holding hands with singer Sela Vave out in Los Angeles on August 17.
Even though Jamie has reportedly already moved on, Katie is embracing the fact that looking good is the best revenge.
