One big question remains in Tom Cruise and Katie Holmes' recent split: How much will Holmes walk away with?

Reuters speculates that the 33-year-old actress may be entitled to $3 million for each year she was married to Cruise. After almost six years of marriage, her take could be around $18 million, the news organization suggests. Holmes has also requested a "suitable amount" of child support for the couple's 6-year-old daughter, Suri (she's seeking sole physical custody).

But Holmes' estimated $18 million settlement is hardly the biggest payout in recent Hollywood history. From the popstar who gave her ex a fifth of her fortune to the sports legend whose astronomical settlement ranks as one of the most expensive ever, test your knowledge of the priciest divorces in Tinseltown.
