Brunette beauty Millie Brady stars in ‘King Arthur: Legend of the Sword’ and attended the glitzy European premiere of the movie in London on Wednesday night (10.05.17). The actress donned a black dress and flashed her knickers but didn’t seem to be embarrassed in front of director Guy Ritchie, and co-stars Charlie Hunnam, Poppy Delevingne, Millie Brady and Aiden Gillen.
