Millie Bobby Brown went Back to Black for her latest late-night celebrity impression. The 15-year-old Stranger Things [1] actress stopped by The Tonight Show Starring Jimmy Fallon [2] on May 22 and had the chance to show off her Amy Winehouse-esque singing skills. She belted out a few lines from "You Know I'm No Good," affecting the late singer-songwriter's rich deep sound.

Millie revealed she's actually been perfecting this impression since childhood, and a deep dive into her Instagram confirms it! Looks like she's been singing like Amy since her kindergarten days. Watch a clip of her sweet tribute to Amy above, and see little 5-year-old Millie sing "Valerie" ahead.
