You'll need a very keen eye, and perhaps the use of freeze frame if you want to see Petia Pavlova's involvement in the Harry Potter world. She's little more than an extra - a nameless witch who drifts along the background in a Diagon Alley scene - but Pavlova continued to work hard at her chosen craft (if you'll excuse the pun), and fame came to her a few years later.
Now all grown up and utterly dazzling, Bulgarian-born Pavlova moved to Los Angeles in 2013 to pursue a career in acting but has also released a number of records under her first name. She has enjoyed particular musical success in the dance and club scene, working with some famous producers. Her Instagram account follows her on her American adventures, which suggest she's also made a completely understandable move into modeling.
