The Daily Star have reported the rest of the line-up has been revealed but did not mention which stars are still in the series.
A source told the publication: “Some of the stars are more obvious than others.
“But the fact that fans have managed to work out who Duck and Queen Bee are is quite incredible.”
The insider added one of the characters is the “toughest” to guess and fans have a long wait ahead of them to find out who is under each mask.
The Masked Singer airs Saturday on ITV at 7pm.
