For those who know the couple, that statement might have been more surprising than calling an end to their seven-year marriage.
The decision to split actually came "after months of nonstop arguing," says a source close to the family. There were issues on a movie set, envy on the American Idol stage, and times that Lopez, 41, feared her husband wasn't faithful.
An Anthony insider disputes infidelity claims and maintains the 42-year-old always supported her career. "They started to see life differently," the source says.
As they move on to the next chapters of their lives, the Anthony insider also says the breakup is for the best. "Though they love, admire and respect each other very much, they just needed to be apart."
