Well holy red hair!
Anne Hathaway has had the biggest hair transformation dying her dark brunette locks a fiery red colour.
Earlier this week, snaps of Hathaway emerged with the dramatic new 'do.
The actress was in New York and the change is for her role The Last Thing He Wanted in Puerto Rico - which she is currently filming.
Hathaway is the queen of transformation.
From the first time we saw her on our screens on Princess Diaries.
Then in 2012 for Les Miserables she famously shaved all her hair off to portray Fantine in the award-winning film.
“I wasn’t expecting it to be such a big deal, because it was my idea,” she said on Live! with Kelly at the time.
“It was something I’ve wanted to do for a long time, and I knew it was something the character did, so I just offered it to the director and he said ‘Yes.’ As it got closer, I thought: I can’t really take it back now.”
And she admits when it came time to actually do it, it was much harder than she anticipated.
