While many of us have been scrimping and saving during the coronavirus pandemic, the same can’t be said for the world’s super-rich. In fact, the world’s billionaires saw their collective wealth increase by 54% between March 2020 and March 2021 to the tune of a staggering $4 trillion (£2.8tn), according to Institute for Policy Studies' (IPS) analysis of data from Forbes, Bloomberg and Wealth-X. And they've been spending some of that cash on some pretty unique things. Click or scroll through a selection of this ultra-wealthy spending, from Kanye West's hologram of his late father-in-law to a spaceflight with Jeff Bezos to a bejewelled face mask commissioned by a Chinese billionaire.

All dollar values in US dollars.
