When newlyweds Said Gutseriev, 28, and Khadija Uzhakhovs, 20, tied the knot in Moscow last weekend, they threw an extravagant celebration that's rumoured to have cost up to £700 million ($1 billion).

The wedding featured celebrity performances from Jennifer Lopez, Sting, and Enrique Iglesias, as well as a custom-made designer dress.

All of it was paid for by the groom's father, the Kazakh-born entrepreneur Mikhail Gutsuriev, according to BuzzFeed. The oligarch, whose oil businesses helped make him rich, has a net worth of £4.3 billion ($6.2 billion) on Forbes.

The bride, Uzhakhovs, is a dentistry student at Moscow University, while Gutseriev was educated at Harrow and Oxford in the UK, The Daily Mail reports. Gutseriev is working as a director for his father's business Russneft, according to an interview in the Russian newspaper Kommersant cited by BuzzFeed.
