It's the most sought after invitation in the celebrity universe – and Amal Clooney, Rihanna and Donatella Versace were named co-chairs of next year's glittering Met Gala in New York.

Held every year on the first Monday in May, the black-tie extravaganza is the chief source of income for the Metropolitan Museum of Art's Costume Institute, reportedly raising more than US$13mil (RM55mil) in 2016.
