She paired the dress with a diamond-and-emerald choker that once belonged to her late mother-in-law Diana, who was gifted the necklace – thought to be worth more than $15 million – by the Queen. 

Five winners were announced at the evening’s ceremony – one for each of the categories on offer at the event: Clean our Air, Protect and Restore Nature, Revive our Oceans, Build a Waste-free World, and Fix our Climate. Each of the five winners was given a $1.2 million (£1 million). 

Ellie has a close connection to the royals, having performed at their wedding back in 2011. 

William and Kate were entertained by a mixture of Ellie’s own material and cover versions, including The Killers’ Mr Brightside, Stevie Wonder’s Superstition and Elton John’s Your Song. 

She is also close friends with William’s cousin, Princess Eugenie.
