The Russians! Billionaire Dmitry Rybolovlev, the 93rd richest person in the world, was all about to settle into his four bedroom/gallery/bar/library/wrap-around terrace palace at 15 Central Park West, when his soon-to-be ex-wife sued him for buying the place to allegedly hide his fraudulently acquired assets. It’s worth… ready for this? $88 million. Take that, Marina Abramović. He didn’t get to enjoy it yet. Nor will he any time soon, as his wife wants $6 billion, making it the most expensive divorce ever.
