And judging by his reaction, neither will Simon Cowell.
It was of course the show's Halloween special and Rylan spooked the pair as Nicole introduced one of her boys.

Xtra Factor host and former X Factor finalist Rylan crept up behind Nicole dressed as the Grim Reaper to leave her screaming.
Simon also looked totally shaken by the sudden appearance, as Rylan took off his mask to reveal his identify before running away.
This week is X Factor's spooky Halloween themed weekend and nine singers remain in the running to be crowned The X Factor 2016 champion.
Those left in the contest include Nicole Scherzinger's Boys - Matt Terry and Ryan Lawrie - and Simon Cowell's Girls - Emily Middlemas, Samantha Lavery and Gifty Louise.
They're joined by Sharon Osbourne's remaining Overs - Honey G and Saara Aalto - and finally Louis Walsh's two Groups - 5 After Midnight and Four of Diamonds.
There were the usual recycled covers of songs like Thriller and I Put A Spell On You as the remaining acts performed live for the fourth time this year.
As always, once the performances are done the public will vote. The three singers with the fewest votes face elimination in Sunday's results show.
Sunday night at 8PM on ITV, the latest results will see another act leave, as well as a performance from reigning X Factor winner Louisa Johnson.
Sunday evening will also see the Jukebox wheeled out again to decide next weekend's theme.
