Each year, the judges enlist a famous adviser to help them whittle the six acts remaining in their category down to just three, ahead of the live shows.
In the past, Cheryl has had help from will.i.am, Tinie Tempah and Will Young, but this year, ‘Don’t Be So Hard On Yourself’ singer Jess Glynne will be at her side in Rome, according to Radio Times.

Meanwhile, Grimmy is said to be joined by Mark Ronson, according to new reports in The Mirror.
The news comes after the revelation that Sinitta will be absent as Simon Cowell’s judges’ houses this year.

In previous years, the ‘So Macho’ singer has been there to offer advice to Simon on which acts should be put through to the live shows, usually while wearing some class of outlandish outfit, like a leaf bikini or a costume made entirely out of fans.
In a bid to shake up the show, this year’s judges’ houses performances were initially intended to be broadcast live.
However, this proved to be causing a logistical headache for producers, and the plans have since been scrapped, although footage of the judges announcing their final decisions will be broadcast live.
Back in series four, 15-year-old Emily Nakanda was one of the early favourites to win the show, but had to back out, after a video emerged showing her violently attacking another teenage girl.Reports at the time said Emily was asked to leave the competition by producers, or risk being axed.

The 'Six Chair Challenge' has been a sticking point with 'X Factor' viewers since its debut in 2013. Many have branded the final stage of Bootcamp cruel, with some hopefuls gaining a place at Judges' Houses only to have to give it up later, but Simon Cowell clearly doesn't mind, as it's back for 2015.

You two have to kiss and make up." (credit:ITV)

A turning point for Cheryl's popularity with the British public came when she was met with a backlash for putting both Cher Lloyd and Katie Waissel through to the live shows, over viewers' favourite Gamu, despite neither of them finishing their performances at judges' houses.Reports later suggested that Gamu could be facing deportation from the UK - adding to the backlash against Cheryl - though the aspiring singer was later insistent this was not the case.
