The four sisters from the Phillipines blew everyone away with their first audition, belting out Bang Bang like an actual polished girl band on a world tour or something.
However it turns out there's already a band called 4th Power, and although who they are is a bit of a mystery, the point is they do exist and 4th Power now have to change their name to avoid any legal issues.
Despite the talent competition already being a boot camp stage, the naming issue has only just been figured out. A source revealed the news to The Sun: "It came as a bit of a shock. The homework should have been done."
It's a bit of a shame because the girls even had a snazzy, in sync way of introducing their band name - involving holding up four fingers. So fingers crossed the '4th' bit stays put!
It 'aint all as though, back in 2011 Little Mix were forced to change their name from Rythmix, and it hasn't exactly held them back from pop stardom.
So what's the new name? Well it's a mystery right now, and in his bid to freshen up the X Factor, Simon Cowell could even put the power into the public's hands when it comes to that decision, ooh.
