my name is ashley olsen today i will talk to u about demi and tiffany. As a ster they love there fans so they cant tell there fighting to there fans so they obsously have to like eachother to keep there fans maybe they are fighting but how will u ever find out make me ask? Never write them a fan letter asking why they are fighting of if they are fighting. When that happened to me i teared up thinking that my fans are lost when a girl wrote me a hate letter so i talked to my sister (Marykate) she told me to ignore it. just leave them they will figure it out of if they are fighting just leave them. door the way no picks about whos better please :)
