Flashing a huge smile as she left the swanky steak house in Covent Garden on Saturday (31 August), the gorgeous star certainly didn't look like someone who chows down on steak and chips very often!
Katherine, who has recently been helping pal Kelly Brook get over her split with Danny Cipriani, showed off her long, bronzed legs in a pair of teeny-tiny black leather shorts and towering strappy black and gold stiletto heeled sandals.
She went for a monochrome look with a simple white sleeveless blouse, adding a pop of colour with a coral manicure and pedicure, and a slick of tomato-red lipstick.
And it wasn't just a smile that Katherine flashed as she got into a London taxi after her meal.
As the blonde singer sat back, she revealed slightly more than she bargained for, treating the waiting paparazzi to a thigh-ful!
Ok, ok, we'll admit it. Someone who can eat steak and chips and still look this good? We're just jealous!
