Anyone engaged to Hollywood actress Uma Thurman would want to shout about it.

So it was not surprising that Arpad 'Arki' Busson, the hedge fund tycoon and philanthropist, should decide to invite pretty much all of London's A-list celebrities to his home in Kensington to show off his fiancee.

Uma, 38, and Arki, 45, announced their engagement in The Times only last week.

And so they came  -  two-by-two  -  to presumably the most star-studded engagement party of the year, held in a vast marquee in the garden.

Lord only knows what the wedding will be like.

Arki has no trouble getting the great and good to his events; only last month he raised £25million for his charity.

Few seemed to be bearing gifts. Worryingly however, artist Damien Hirst arrived carrying a box.

Not big enough to fit in a cow but possibly a pickled mouse or even a small cat. Lucky Uma.
