Watch Rylan scare Nicole Scherzinger and Simon Cowell live on the X Factor

Updated: 

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.

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

One person even deemed it the best performance of the night.

Bring back Rylan?
