It’s messy enough when a mortal couple gets divorced, but when it’s a wealthy celebrity pair like Kim Kardashian and Kris Humphries, things get even more complicated.

Case in point: after Kardashian pulled the plug on her much-hyped 72-day marriage to her NBA player husband, many wondered who’d get custody of her massive 20-carat diamond engagement ring.

Now sources close to the couple say a clause in their prenuptial agreement states that if the two divorce, Kardashian can retain possession of the sparkler — if she pays her estranged husband for it.

The clause is particularly curious since without it, the ring would’ve automatically gone to the bride. Regardless, insiders say the reality star loves it so much that she’ll shell out the funds necessary to keep it — which could be upwards of $2 million.
