The RL Hannah Baker has a whole new look!聽Katherine Langford, who was catapulted into fame with her debut television role as the lead character聽on the ultra-popular Netflix drama聽13 Reasons Why, has just聽ditched her聽signature curly brunette lob, and聽the star鈥檚 new look聽will definitely take you by surprise.

Langford, 21, was spotted on the set of聽upcoming sci-fi flick聽Spontaneous聽wearing a T-shirt, jeans, sneakers 鈥 and a whole head of long, bleach-blonde hair that had us doing a double take. Seen both standing in the woods and struggling as she鈥檚 carried away a group of men in white suits with her platinum tousled 鈥榙o, there鈥檚 no trace of the fictional teen we came to know and love.

In her place, we see Mara Carlyle, a teen struggling to聽get to the bottom of a mystery that involves the聽spontaneous combustion of her classmates (yes, really!) alongside Granite Flats alum聽Charlie Plummer (Dylan).

Langford isn鈥檛 the first 13 Reasons Why alum to go from one end of the hair color spectrum to the other: Just two months prior, executive producer Selena Gomez did the same聽while making her first post-surgery appearance at the American Music Awards.

Kudos to both ladies for going for bold!
