Christmas Special

Paddy McGuinness is joined by Celebrity Investigators Jimmy Carr, Alison Hammond and Amanda Holden. Leona Lewis is the guest star for this festive special, hoping her musical expertise can help spot the imposters.

The Celebrity Investigators help ice cream man Dev from Stretford in Manchester and his celebrity partner Gabby Logan to tell the difference between the good and bad mystery singers without ever hearing them sing a note. With a line-up including a vicar, a footballer and a ‘snow queen’, they may have their work cut out. With £10,000 on the line, the last mystery singer standing will reveal if they are a good or a bad singer in a duet with Leona. There is also a brand new round, Home Truths, in which Dev and Gabby get the opportunity to snoop around the mystery singers' homes.
