Demi Lavoto, Selena Gomez, Miley Cyrus, and Mandy??

Demi and Selena have a show like Mandy and Miley, right? Well, they had a feud about 1 or 2 months ago. I wonder if they are still friends. I don't think Miley or "Mandy" have a conscience. I think it was not right to make fun of her friend, Selena, like that. What do you think?
