Are you excited for the premiere of the X-Factor live shows tonight? The X-Factor auditions are always fun and heartwarming and this year's addition of the Four Chair Challenge was super intense, but now the competition is about to get on a whole other level.
When Season 3 kicked off, M gave you The ABCs of X-Factor and now we're celebrating the start of the live shows with a guessing game. Do you know which former X-Factor contender is older than the other?
We rounded up celebs who got their start on either the UK or US versions of the show — stars like Cher Lloyd, One Direction, Fifth Harmony, and Emblem3 and pinned them against other X-Factor alums. Can you guess who's older?
Click through the gallery to play the game! How many did you get right? Make sure you to tell us your score in the comments!
