The 17-year-old actress - who plays Eleven in the hit Netflix series 'Stranger Things' - made a powerful speech during the awards ceremony on Saturday (13.03.21), when she won the Favourite Female TV Star and Favourite Movie Actress gongs.

Millie said: "I've been in this industry where I've had my triumphs, my struggles, and I'm incredibly grateful for all the women over the world that continue to redefine and shape women in TV and movies.

"I have great inspiration, so that is why accepting these rewards. We will continue to fight against stigmas and stereotypes and I am incredibly grateful to be part of that movement."

The actress was previously made UNICEF's youngest-ever Goodwill Ambassador and Millie has insisted she's determined to "shine a light" on issues that she considers to be important.

The teenage star explained: "I will speak out for the millions of children whose voices have been silenced for far too long.

"I will shine a light on the issues that vulnerable children have suffered around the world. Including representing them at places they haven’t yet had a seat at the table."

Millie was thrilled when UNICEF asked her to become one of their Ambassadors.

She recalled: "UNICEF is the biggest and best children’s organisation in the world. I have always been so blown away by what they do for children’s rights.

"I am very passionate about children getting the education they need, providing vaccines for them, protecting children against violence and ensuring they know what their rights are.

"Being named an ambassador – honestly it was one of the craziest situations. I can’t even put into words how I felt, but it was just so exciting."
