Hayden Panettiere and Milo Ventimiglia have finally split up. I'm sorry but how many were really rooting for these two? It was really gross seeing the two together, due to their age. Now some are stating that they believe it is Hayden's age and how she likes to act it. I don't see nothing wrong with her wanting to party with others her age, but for someone like Milo this could pose a problem. Milo has always been more of a by himself type of person, Hayden seems to be the life of the party type of girl. Now she'll be everywhere.
