Simon Cowell has confirmed that Tulisa is 'head judge' on The X Factor this year

Simon Cowell has appeared to confirm that noted vide­o­di­ar­ist Tulisa will return to The X Factor this year as 'head judge'.

It's not exactly a surprise but now Tulisa's return seems to be a done deal, with Cowell saying: "I under­stand Louis & Gary are squab­bling as to who is head judge..since @OfficialTulisa won last year, she is the reigning head judge."

Gary had tweeted yesterday: "I hear there's a lovely lad from Ireland joining me on #XFactor.Congrats Louis! One of these years you'll be head judge."

As there are four judges and no one has the casting vote, we were never really sure what all this 'head judge' business was all about but there you have it, maybe it's just a dodgy blowjob reference.
