The volumised Amanda Seyfried was spotted filming scenes for her new film, Lovelace, yesterday, which sees her play the famous 1970s porn star, Linda Lovelace.

The role has resulted in a dramatic change of hairstyle for the star. Seyfried has swapped her long, blonde locks for a curly auburn do and with big 70s hair comes a seriously retro wardrobe.

Something tells us the curls won't be staying, but will Seyfried stick with her darker hair colour or is she better blonde?

Let us know below and see which other celebrities have been transformed from blonde to brunette.
