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 pounds ($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 Gutseriev, according to BuzzFeed. The oligarch, whose oil businesses helped make him rich, has a net worth of 4.3 billion pounds ($6.2 billion) on Forbes.

The bride, Uzhakhovs, is a dentistry student at Moscow State 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, as cited by BuzzFeed.

Take a look at a selection of photos and videos from the couple's ridiculously expensive wedding below:

The bride's gown was designed by Elie Saab and imported from Paris. The dress is worth up to 18,000 pounds ($25,925), according to The Telegraph.

It was so heavily embellished with beads that it weighed nearly 2 stone, or 28 pounds. The bride also needed help walking around in it.
