Heather Small found herself involved in a comedy collaboration on I Can See Your Voice tonight.
Each week the celebs are joined by a special guest to help two contestants attempt and tell the difference between good and bad mystery singers - without ever hearing them sing.
With £10,000 on the line, the players try to pick out the bad singers based on a handful of clues, questions and lip-sync performances.
The last mystery singer standing will only reveal if they are a good or a bad singer in a performance with the week's guest, which on Saturday was Heather Small.
In the final round players Caitlin and Kristen from Warrington found out whether they had chosen a good singer for Heather to duet with (winning them £10,000) or whether the singer was in fact bad and had therefore stolen the £10,000.
The singer, known as ‘Fashionista’ turned out to be terrible as she performed Moving On Up with Heather.
As a result, Caitlin and Kristen missed out on the cash and it instead went to 'Fashionista', who was a model and blogger called Maria Luxe from London.
After the performance, a shocked Jimmy asked Maria: "Have you even heard music?!"
But Maria had the last laugh, walking away with £10,000.

Next week's guest star is Alexandra Burke as brothers Joe and Dan from Middlesbrough try to tell the difference between the good and bad mystery singers. Those on the line-up include a singing scientist, a prison officer and an electrician.
Further musical guests on the series include Nadine Coyle, Danny Jones from McFly. Ricky Wilson from the Kaiser Chiefs, Louise Redknapp and Ronan Keating.
