Lily Allen recently reflected on one of the most regrettable decisions of her life.

The British singer was approached to perform private gig for a whopping £61 million.

Allen revealed on her twitter account that she turned down to play live stream a concert to the virtual world 'Second Life' "about five years" ago.

All the 28 year-old would have had to do was sing in front of a computer screen, without leaving her home, so people in the game would be able to see.

At the time the unknown organiser offered Allen "hundreds of thousands of Bitcoins" which wouldn't have been worth as much as they are now.

In today's market, a Bitcoin is worth around £610 each, according to The Telegraph, so the 'hard Out Here' singer missed out on a potentially huge fortune.

Her tweet finished with, "'as if' I said. #idiot #idiot."

Allen won't be hurting too much though as the 'Not Fair' singer has a reported fortune of £6 million, having said that, a fortune ten times bigger would be very nice!

Lily remerged on the music scene in late 2013 after her second child, Marnie Rose, was born in January of that year. After a four year hiatus she released 'Hard Out Here', a track highlighting he music industry's sexualization of young female acts.

Allen also reached No.1 for three weeks in a row with a cover of Keane's 'Somewhere Only We Know', partly in thanks to featuring on the John Lewis Christmas advert.
