Which actress won an Oscar for 'La La Land'?

Karen 7, I agree all the cast was great in this one.. I love John Legend.. yes and I thought the movie should of won best picture

Good movie, bad ending. Musicals should have a happy ending. Not ending with a knowing glance...

I like Emma Stone. I like Ryan he should of been recognized for this role. He is very good his day will come. This movie should of won for best picture..the work and the music was amazing. John Legend. Love his music.. his voice is so good
