Reckon you can tell the Union J boys apart with your eyes shut? We’ve devised a quick fire quiz to help you prove it.
Keep those fingers off the Google button and find out how quickly you can tell the Union J members apart. From individual tattoos and haircuts to the group’s record labels and album tracks, these are the things all jcats know… better than they know themselves.
How did you do? Let us know @TicketmasterUK.
