News about the LOL plot has surfaced, and it will apparently be a very mature role for Miley. According to Hollywood Life Miley's character Lola is quite rebellious and gets involved in some questionable activities. I don't want to reveal any spoilers so if you want the details go to Hollywood Life.
I think it's good Miley is doing a role like this. She's at a time in her career where she needs to push her acting limits and this seems like a good role to do that. If this movie does well doing an edgy part like this could help her get bigger "grown up" roles in the future.
