Kristen Stewart

Kristen Stewart decided to part with her locks to make her life easier whilst shooting the movie 'Underwater'.

During an appearance on the 'Today' show, the 'Twilight' actress revealed she shaved her head to add to her character in the film.

She said: "I'm doing a movie in a couple of weeks called 'Underwater' and I play a mechanical engineer who is working on an oil rig on the bottom of the ocean floor, so for me it's practical.

"I mean I'm not going to be able to have touch-ups once I put the helmet on so I must shave my head! I've wanted to do this for a long time for novelty's sake, just because at some point in your life you want to be able to do that. It feels amazing."
