Kristen Stewart Reveals Why She Shaved Her Head: 'It's Practical'

By
Expect to see Kristen Stewart's buzz cut on the big screen.
The 26-year-old actress shared on Thursday's Today show that she wanted to shave her head before filming her upcoming movie, Underwater, where she plays a mechanical engineer that's working on an oil rig that's at the bottom of the ocean floor. "It's practical," she quipped. "I mean, I'm not going to be able to have touch-ups once they put the helmet on my head."
Stewart did admit that she wasn't required to chop off her hair for the role, though director William Eubank did suggest it. "I've been wanting to do this for a long time, just for novel sake," she explained. "It feels amazing. I just want to head bang all day."
Over the past few years, Stewart has been more open about sharing her life -- hair and all -- with the public, which is a far cry from when she was promoting the Twilight films. "People started really caring about the details of my life when I was pretty young," Stewart reminded ET while promoting her new film, Personal Shopper. "And since then, the media and our interaction with celebrity has changed enormously, even in that short time period. So I kind of have navigated it naturally and adapted."
