Simon, who's mentoring the boys, chose Austin Drage (the one who cries all the time), Scot Bruton (ex-Pontins Blue Coat from Manchester) and Eoghan Quigg (the 16-year-old with highlights from Ireland).
Dannii got the over 25s and went for Daniel Evans (the pool-cleaning widower), Rachel Hylton (ex-drug addict and motor-mouth) and Ruth Lorenzo (the Spanish-born PR consultant).
Louis is looking after the groups and for his final three he settled on Bad Lashes (the four-piece girl group from Durham), Girlband (the other set of four girls that were in Boot Camp) and JLS (the four guys who no one ever doubted would make it through).
And lastly, Cheryl, who's looking after the girls, decided on Alexandra Burke (who Louis kicked off Boot Camp three years ago), Diana Vickers (the quirky blonde student from Lancashire) and Laura White (the big-lipped jazz singer from Manchester).
We reckon all the judges have made pretty good choices. The bookies have got Laura White down as their favourite to win. Who are you putting your money on? Join our chat.
