Following a three-year hiatus, Simon Cowell has returned to the panel as head judge, having told viewers that he "just had to come back".
Cheryl Fernandez-Versini has also made her comeback to the ITV1 singing show and has already given fans what they want on more than one occasion - the 'Cheryl Tear'.
Bringing a new dynamic to this year's X Factor is Spice Girl Mel B, full name Melanie Brown, and her one-liners have already had the audience cracking up.
As one contestant raved about Cheryl, Mel frankly asked: "What am I? Chopped liver?"
And then of course there is good old X Factor stalwart Louis Walsh, the man behind boybands Boyzone and Westlife (and originally Girls Aloud, but Cheryl likes to forget that).
But who is your favourite judge so far? Are you delighted to have Simon and Cheryl back, or does Mel B Spice Up Your X Factor? Perhaps Louis brings you joy due to his familiar Irish face?
