The 'Britain's Got Talent' beauty has announced she has joined Louis Walsh in Ibiza, Spain, to help him pick his three acts for the live shows, while the 'This is What You Came For' hitmaker will give Nicole Scherzinger some advice on her category.

Speaking to 'Good Morning Britain', the brunette beauty explained: "Louis is crazy, we had such a laugh, I tried to advise him but I can't be held responsible."

Calvin, on the other hand, seemed to have great fun during his time at Nicole's house in Nice, France, as he documented his experience on his Snapchat account.

Nicole said in the clip: "We're just chilling here at my villa in the South of France," to which Calvin replied, "Quite nice."

Calvin's appearance on the show will no doubt come as somewhat of a surprise to viewers when the scenes are aired on screen as it was previously claimed he'd been slap with a "lifetime ban" after he stormed the stage in 2009 when Jedward were performing with a pineapple on his head.

He said at the time: "As far as I'm aware, in fact definitely, I'm not allowed back on that show. Sadly that's it for me and 'The X Factor'."

Meanwhile, it's not yet known who Sharon Osbourne has asked to be her special judge and it's believed Simon Cowell will ask his close friend Sinitta to be his helping hand again.
