In 2014, she starred with James Franco and Chris O'Dowd in Of Mice and Men on Broadway, which earned her positive reviews.

The 24-year-old hasn't acted since — save for a cameo in the finale — and has instead focused her energy on her hard rock/post-grunge group, The Pretty Reckless, of which she is the singer.
