The British actress joined a slew of other famous faces for a showing of The Curious Incident of the Dog in the Night-Time on Tuesday evening (30 June).
We're used to Nathalie dressed in robes as her Game of Thrones character Missandei - last night she was sporting a very different ensemble (obvs)!
The 26-year-old looked fantastic in a leopard print skirt and simple white blouse, teamed with heels and a cute green clutch bag.
Officially our new girl style crush!
As well as Game of Thrones, you probably recognise the star from her days as Sasha Valentine on Hollyoaks. She also appeared in this year's Furious 7.
Off camera, she's just helped raise enough money to provide her godson with an autism service dog. Training such a dog costs around $8,000. She's now hoping to raise enough money to help another family acquire their own autism service dog. Find out more here.
