Former favourite Lucie Jones' departure last week proved that nobody is safe in this competition, as the twins John and Edward survived yet another week (thanks Simon! *waves*) Now, the battle for the X Factor crown continues as the seven remaining acts compete to win viewers' votes by singing Queen songs. Instead of Louis giving Jedward Another One Bites the Dust, he's landed them with Bohemian Rhapsody. The mass onstage confusion will be something to behold. As always, the Xtra Factor can be seen on TV3 at 9.30pm, and will see Holly joined by Calvin Harris and 'Preston'. The only Preston we know is from the Ordinary Boys/Celebrity Big Brother fame so one can assume it's him.
