Jessica Alba can not decide on her hair color. At one time she is blonde, then she changes it to brown. Moreover, by far those changes are not always work-related.
Recently Jess became blond again. Some rumors say that she plans to act in another “Fantastic Four” movie, however it is equally possible that she simply needed some changes. Perhaps its the young mother syndrome, when a woman spends a lot of time doing pleasant, but sometimes tiring activities with the baby, she would occasionally have urge to do something for herself as well.
