I really would like to know the name of this song if you could help PLZ :)?

I have the opening part of this song stuck in my head but can't find the song UHHHH. The opening i think goes like this "Fire burning deep within my soul"?? i think sorry but the music video has like her sitting on a chair then there is like cups of water all over and then there is this person in a room dancing and there like flour every where and it starts to make the room all light fog-ish. If you could tell me the name of the song that would AWESOME PLZ O and the song sounds like something from like twilight but i didn't;t see anything that looked like the song but maybe i missed it I also first saw the song on MTV.
