We love it when celebs mix things up, especially when it comes to their hair colour and Katherine Heigl is the latest star to ditch her blonde waves for a sleeker brunette do.

We didn't recognise the actress at first but maybe maintaining brunette locks is much easier than blonde, especially when you're juggling a new baby with your career.

We like the change and think Katherine manages to pull it off. What do you think? Better as a blonde or beautiful as a brunette?

Who else had braved the dye bottle?
