She sang a beautiful rendition of Ave Maria before breaking into Katy Perry's Firework.

Millie Bobby Brown is one of the world’s favourite actresses, which is impressive considering she’s only 13 years old.

The British actress played the role of Eleven, a mysterious character with telekinetic powers in the Netflix original series Stranger Things, and her powerful performance has won her thousands of fans across the globe.

On Friday, Millie proved that she’s not just an exceptional actress but a wonderful singer too. Taking to the stage at Argentina Comic Con in Buenos Aires on Friday, she sang a gorgeous rendition of Ave Maria before breaking into Katy Perry’s Firework.

Naturally, the crowd went wild for her, and now it seems the young lady has an even brighter career ahead of her than we thought.
