The Downton Abbey actress looked utterly beautiful in her delicate pale blue gown while promoting the fairytale in Mexico on Thursday (5 March).
Lily has been looking sensational throughout the promo tour for Cinderella, choosing very princess like, ethereal frocks for the red carpet.
In Mexico, she was joined by her co-star, Game of Thrones' Richard Madden, who plays Prince Charming to her titular character. He looked very handsome and royal indeed in his black tux.
We CANNOT wait to see this!
Cinderella, directed by Sir Kenneth Brannagh, arrives in cinemas on 27 March.
