The X Factor airs tonight at at 8:35pm on ITV.
Already on episode 13 of series 15, the talent competition has yet to make it to the final 12 who will perform live to win.
There are another 24 acts travelling to judges houses in a bid to win a place in the live shows.
One such judge is Robbie Williams, former Take That singer.
Robbie Williams, 44, is one of the most successful musicians and pop stars in the world.
He has sold millions of records, sold out stadiums and even performed at the World Cup 2918 Opening Ceremony.
The star rose to fame in the 1990s when he was a member of boy band, Take That.
He is now an X Factor judge and one of the best-selling artists of all time, but how much is he worth?
According to reports, Robbie, along with his wife Ayda, was given a £10 million contract to appear on the 2018 series of the X Factor.
The star has decades in the music business and comes with priceless industry knowledge, no doubt securing his spot as a judge.
The star is the best-selling British solo artist in the UK and the best selling non-Latino artist in the US.
With such an achievement under his belt, Robbie is reported to be worth a staggering £150 million ($200 million), according to Celebrity Net Worth.
It could be said that Robbie’s hugely successful career is all down to his mother, who took him to the audition for Take That.
Take That quickly became a pop phenomenon, with the band producing hits such as Back for Good, Pray, Never Forget and Kidz.
Skyrocketed to worldwide fame, Robbie eventually leaving the band in 1995 to embark on a solo career.
Earning him a whopping £3 million, Robbie then went onto release his multi-platinum debut album, Life Thru a Lens.
He banked another £6,842,000 when he released his second album, I’ve Been Expecting you.
By the naughties Robbie was a household name, releasing nine studio albums including his biggest grossing album of all time, Swing When You’re Winning, bringing him in£5,500,000.
Hi 2006 tour, Williams’ Close Encounters, even landed him in the Guinness Book of World Records, selling 1.6 million tickets in one day.
Around 12 years later, and with millions more banked and countless new albums released, Robbie has become a judge on X Factor 2018.
Robbie’s wife, US actress Ayda Field is also starring on the X Factor as a judge, with the couple reportedly banking £10 million for their appearance.
Following the announcement of himself as an X Factor judge, Robbie admitted the “millions” of pounds on offer persuaded him to do the show, despite previously turning the role down.
Not short for cash, last year Robbie and Ayda Field moved into a £17 million home in Kensington that used to belong to film director Michael Winner.
Starring alongside her husband, Ayda has a pretty impressive fortune of her own, worth £26.4 million ($35.5) following her 20-year career in the film and television industry.
