BILLIE Eilish has ordered the "biggest takeaway order ever" from a popular city centre restaurant.

The singer-songwriter, who performed a sold-out gig at the Hydro last night as part of her Happier Than Ever world tour, ordered £1000 worth of food from Buck's Bar on West Regent Street.

The massive order, which appeared to include a selection of chicken wings, was packed up and sent to the Finnieston venue for the Bad Guy singer's crew to enjoy. 

A post on Buck's Bar's Facebook page, alongside photos of staff with the order, read: "Biggest Buck's Bar takeaway order ever. 

"@billieeilish knows how to look after her crew.

"£1000 takeaway order packed up and off to the @ovohydro for all her hard-working team. 

"Well done to the team at Buck's Bar WRS for supplying the goods and looking after Billie's crew over the last few days. 

"What a bunch of legends."

On Monday, Eilish was spotted outside popular vegan restaurant Mono in Merchant City alongside her co-writer, producer and brother, Finneas, reports the Daily Record.

She was seen taking pictures with excited fans.
