The Harry Potter star won the ceremony’s first ever gender-neutral title, picking up the best big-screen actor gong for her role in Beauty and the Beast.
On the night, Watson wore a pair of 18ct white gold diamond spike earrings from the Natalie K for Forevermark range.
She completed her look with a Kitx Fall metal disc sequin dress and a pair of SUSI Studio Hey Simone sandals.
Watson said of the new award category: “MTV’s move to create a gender-less award for acting will mean something different to everyone.
“But to me, it indicates that acting is about the ability to put yourself in someone else’s shoes. And that doesn’t need to be separated into two different categories.”
Describing her win as “meaningful”, the 27-year-old noted that the genderless award said “something about how we perceive the human experience”.
