Eurovision announced the lineup several weeks ago but semi final commentators Rylan Clark and Scott Mills told the Liverpool Echo there are still a few surprises that even they don't know about.
Discussing the secret perfomer, Scott said: "There has been some stuff happening where it's been a completely closed set so nobody has been allowed to go in there." Rylan said: "There are some secrets."
Scott added: "So what's going on there? No one will tell us I promise you." Rylan jokingly admitted everything the Radio 2 DJ said was true but after one or two drinks he "may spill some of his secrets."
