British pop star Lily Allen missed out on a huge pay cheque by turning down a job because the payment was in digital currency bitcoins.

The Smile singer was asked to stream a live performance on online gaming world for a payment of "hundreds of thousands of bitcoins", but Allen quickly dismissed the offer.

The value of the currency rocketed to around $900 (£600) per bitcoin in early 2014, and Allen now realises she could have made millions.

In a post on her account, she writes, "About 5 years ago someone asked me to stream a gig live on Second Life for hundreds of thousnds (sic) of bitcoins, 'as if' I said. Idiot."
