Just four years ago Rylan was scaring Simon Cowell on a weekly basis with his performances on X Factor and he returned to do the same during Saturday night’s Halloween special.

Dressed as the grim reaper, the Xtra Factor presenter crept up behind Simon and Nicole Scherzinger during fright night causing them both to squeal.

Nicole leaped out of her seat in terror.

But the person who pulled the best face had to be Sharon Osbourne.

Worth watching #XFactor tonight purely for this moment. pic.twitter.com/7AmefFxqKh

Always the crowd favourite, Rylan was lauded by fans for his trick.

Can Rylan make Nicole scream again? That was hilarious. #XFactor

With Rylan doing what he did earlier to Nicole, the Xtra Factor is going to be a good watch #XFactor #XFactorFrightNight
