Jittery Jedward were Under Pressure last night after their song for tonight's show was changed at the 11th hour.
Queen stars Roger Taylor and Brian May met the finalists this week and twins John and Edward Grimes were meant to sing the band's Radio Ga Ga hit. But the Dublin teenagers were told to swap with Jamie Archer and will now perform Queen's 1981 song with David Bowie, Under Pressure.
An X Factor insider revealed: "The twins were struggling a bit with Radio Ga Ga so a decision was made to change their song.
"But they're freaking out now as they're having problems remembering the words for Under Pressure and they're worried they'll mess it up. For the past few weeks, their performances have been ambitious but there is no big production to hide behind this time.
"There's some big notes in this song too so that's another worry."
