There have been plenty of exorbitantly expensive celebrity divorces over the years. Mel Gibson, Michael Jordan, and Steven Spielberg were each involved in splits that cost $100 million or more. Other well-known figures, like Larry King, Mickey Rooney, and Elizabeth Taylor, are famous for getting hitched--and subsequently divorced--more times than you can count on one hand.

But none of these divorces ranks among the all-time costliest in history. Neither does the divorce of Donald and Ivana Trump (she reportedly got $25 million plus a $14 million estate in Connecticut), or Donald Trump and Marla Maples (a measly $2 million, thanks prenup!). The collective net worth of Brad Pitt and Angelina Jolie is reportedly around $400 million, but even their forthcoming divorce settlement will be relatively small compared to some truly colossal splits.

Below, we've assembled a list of the most expensive divorces in history—some believed to have run into the billions.
