Flipping 'eck! Karen Gillan has only gone and shaved off all her gorgeous hair! And the former Doctor Who star looks almost unrecognisable without her long auburn locks.
Karen still look totally gorgeous though. And not everyone can pull of the bald head look - just ask Britney Spears.
Ok, that's not a fair comparison really - poor Britters wasn't quite herself during the head shaving incident. But our point is, not everyone can do bald.
Karen, who is best known for playing Amy Pond in sci-fi series Doctor Who revealed her new look at Comic Con in San Diego.
She appeared on stage during a Q&A session, and not only did she reveal that she's playing Nebula, the super-villainess in Marvel's upcoming Guardians of the Galaxy, she also revealed that she has shaved her head by pulling off her wig while answering questions.
Now that's is how you drum up publicity for a movie!
The cast of Guardians of the Galaxy also includes Benicio Del Toro, Lee Pace, Glenn Close, John C Reilly, Chris Pratt and Zoe Saldana - we don't, at the time of going to press, know if they've all shaved their hair off too.
If you're sad about the loss to Karen's gorgeous hair you can see it again in her next film romantic comedy Not Another Happy Ending, which closed this year's Edinburgh International Film Festival.
