It appears as though Emilia has been making the most of her time off after finishing filming on season eight of Game Of Thrones.
Just last month, the blonde beauty put on a boob-baring display during a trip to Italy.
Sporting a white swimsuit, she gave her social media fans a glimpse of her sensational physique and cleavage.
Proving to be a natural beauty, she showcased her radiant complexion and stood out with her red lipstick.
Emilia’s revealing snap whipped her fans into a frenzy, receiving many compliments from her followers.
Game Of Thrones season eight is expected to return early next year on HBO.
