Kristen Stewart is revealing her biggest red carpet regret, and it's a look she wore when she was just kicking off her career. "I think the pictures that they took at the premiere of Panic Room," Kristen tells Marie Claire UK. "It's like a popular image to show from when I was younger ... And I look at that and I'm like, 'Oh... my... gosh.'"
Kristen was just 12 years old and going through an awkward time style-wise. "I had like these baby hairs and I was being weird about them, so I was like, 'I'm just gonna cut them off.' And I had like these little things like poking out from under my hair and behind my ears, and a ridiculous outfit," the actress says. "I did not know how to get dressed up at that age at all, I didn't even know what I liked. I was just like completely… a goofy kid."
