London Marie Sherwood "What Hurts the Most" song on myspace?

Help me find who is singing this! One of my friends on myspace posted the story about London Marie Sherwood again today but this time it's got the song "What Hurts The Most" by Rascal Flatts, except it's a girl who is singing it! It's BEAUTIFUL! Does anyone know what I'm talking about?? I'm dying to find out who this is singing!!!
