Anne Hathaway stunned with her pixie cut for all of 2014, 2013 and good chunk of 2012 after chopping her hair for her Oscar-winning role in "Les Miserables."

It seemed she'd become all too comfortable with her short look, even switching it up and dying her hair platinum blonde for the 2013 punk-themed Met Gala.

But it appears the actress is finally letting her hair grow, as she premiered a chic bob hairdo at the American Cinematheque Awards in Los Angeles on Oct. 21.

We haven't seen Anne since she stepped on the red carpet at the 2014 Met Gala in New York City in May -- and her hair was still super short then. And any shots of her filming her upcoming comedy "The Intern" show the 31-year-old in a long wig.

No wonder we didn't notice the lengthening of her mane!

While celebrating "Interstellar" co-star Matthew McConaughey, who was honored at the American Cinematheque Awards, Anne showed off her new 'do.

Wearing a rope-adorned Christopher Kane dress, the actress topped off her look with emerald drop earrings and rouge lipstick.

Will she continue to let her tresses grow down her back? Time will tell!
