The 35-year-old singer filed for bankruptcy under his real name, Duncan Inglis, just weeks before he is due to embark on tour with the 'All Rise' boy band for their comeback tour, reported Daily Express.
The order was made on September 12 at the High Court in London.
This financial blow comes after the group's company Blueworld Ltd went into administration in May.
"There was no warning that the band had money problems. This has come as a complete shock. Letters have been sent out by the administrators to creditors who are owed substantial sums by the band," a source said.
Meanwhile, Duncan, will be hoping to cash in when Blue perform their first big tour since reforming in 2009, thanks to the popularity of ITV2 show 'The Big Reunion'.
Duncan and Anthony will be joined by Simon Webbe and Lee Ryan on the road in October and November.
