Blake Lively's most well-known character - Gossip Girl's Serena van deer Woodsen - is famously blonde, but last night Blake showed off some brand new red locks.
She's the latest in a long line of stars including Rihanna and Drew Barrymore to go red recently, and she's chosen a lighter strawberry blonde colour.
Blake showed off her new hue at the Time 100 Gala in New York, wearing a gorgeous aqua gown, where she was honoured as one of the most influential people of the year alongside Glee's Chris Colfer.
Her career is on fire at the moment after some fantastic high profile roles, and she's set to star alongside Aaron Johnson, Emile Hirsch and others in the new film from Oliver Stone - Savages.
Blake's something of a chameleon, as she's also flirted with brunette locks in The Green Lantern, where she costars with Ryan Reynolds. Still, she's keeping quiet so far on if this change is for a role.
Either way, she looks fantastic!
