Causing jaws to drop in a floor-length burgundy Burberry dress that was custom-made for the Brit beauty, Keira opted for screen siren glamour with smokey eyes and her hair swept to the side in an undone up-do.
Meanwhile, Michael rocked a cool casual look and Viggo looked super dapper in a white suit buttoned-up over a black tie.
All three stars hit Mayfair hot spot, 34, for supper and a some serious celebration that saw Michael and Keira turn the restaurant into a dance floor!
