Obviously Jackson has a successful career and income on her own, but that doesn't necessarily mean she won't get money in the divorce, especially considering Al Mana is a billionaire.

In fact, there have been reports that Jackson could get up to $200 million in the divorce, which Ziegler says wouldn't be all that much for someone like Al Mana.

"$200 million tax-free would be a huge chunk of money, but for someone that's worth $1 billion it may not be as big of impact," Ziegler told us. "When people are entering into prenuptial agreements they need to consider what their net worth is at the time, and then in the event of divorce, if they can be self-supporting. I think here Janet has enough money to take care of herself, so there's definitely no alimony."

However, as you probably recall, Jackson gave birth to a baby boy, Eissa Al Mana, with Al Mana in January. A source says the baby will stay with his mother, which means child support will likely be on the table.
