Renee Zellweger is shocked she still has a full head of hair - because she has dyed it so many times for movie roles.

The Bridget Jones’s Diary star has sported both blonde and brunette locks over the years, and insists she’s had some interesting hair colours as a result.

She tells InStyle magazine, "(It’s amazing) it’s still attached to my head, by the grace of God. What I didn’t know is the temporary stuff stains the inside of the shaft, so you can’t get it out. Ronald McDonald red. Then it faded to pumpkin. Then it was pink, then mango. Mango hair - now that’s a look."
