What is the singer I'm thinking about?

I know this is stupid but I remember this music video that I really liked but I can't remember the singer's name. It was a music video of a girl in a trailer with a guitar. I can't remember the song name either. I think the video started with her sitting at the entrance to the trailer and then there were scenes when she was inside as well.. She had highlights in her hair.

The most annoying thing is that I even remember her face but can't find a way to remember what her name was :P

Hope somebody can help me.

I know I don't remember a lot... :(
