When the scions of two of Russia's wealthiest families get hitched, no expense is spared.

And the LA nuptials of Lolita Osmanova, the daughter of energy tycoon Eldar Osmanov, and millionaire Albert Avdolyan's son Gaspar did not disappoint, with a rumoured $10million splashed on celebrity entertainment, rows of classical violinists and thousands of candles and fresh flowers.

The couple chose Hollywood's iconic Dolby Theatre - home of the Oscars - as their venue, and the after-ceremony entertainment was provided by none other than Grammy award-winning megastar Lady Gaga.

Up to $500,000 is believed to have been spent on flowers alone for the lavish ceremony, and Russian newspaper reports said anyone hoping to top the nuptials of two of its most glamorous young exports would have to hold their ceremony in space.
