Last week many were surprised to hear about the split between Arnold and Maria. However, the revelations this week have explained the back-story. It turns out that Arnold had an affair and fathered a child with one of their household staff members 10 years ago. The staffer reportedly retired just this past January. So this means that this staffer has been in their house for the last 10 years while she was raising their child. Arnold has asked the press to focus on him and leave his wife and kids out of the focus. However, you can bet that the staffer and their child will certainly be hounded by the press.
