The young star burst into Hollywood with her Oscar-nominated performance in 2010's True Grit. Now she's breaking out again, this time as a pop star (and a key member of everyone's favorite girl squad).
She may be only 19 years old, but Hailee Steinfeld has been famous for six years. She first vaulted to international attention at age 14 when her performance as a gun-toting farm girl in the Coen brothers' 2010 epic, True Grit, earned her an Oscar nomination for best supporting actress. "Entering Hollywood so young, I don't think I was aware of anything, other than the fact that I was having fun, in a serious way," Steinfeld says, adding sheepishly, "I had no idea that asking 500 questions on set every day was too much."
