Did You Catch Simon and Cheryl's X Factor Blunder?

Last night, 17-year-old Louisa Johnson - mentored by Rita Ora, as you can see - won The X Factor, nabbing the title from the dual mitts of Reggie N Bollie, mentored by Cheryl.

Now that we have the all important facts out of the way, the real talking point of last night's final results show occurred during winner Louisa's performance of her new single - a cover of Bob Dylan's Forever Young (for realz)...

For those unable to view the clip, it features both Cheryl and Simon simultaneously taking to their feet prematurely to applaud during a rousing key change pause. Given Cowell was partially responsible for the success of Westlife, he'd be well versed (apologies) in the ways of the all-important key change.

For those gunning to see another close up of Louisa and Rita's WE'VE WON reactions, here you go.

Were you glued to proceedings last night, or did you stop watching yonks ago?
