Gary Barlow heads off on a charity drive from Land's End to John O'Groats today accompanied by Professor Brian Cox, Radio 2 DJ Chris Evans and Top Gear's James May.
The celebrities will travel in the same car - a pink Rolls Royce with an "FAB1" numberplate - and are expected to arrive in John O'Groats at around 4am on Friday morning.
Barlow and May spoke to Daybreak about their journey - with a little help from Cox:
Television bosses want the duo to provide "fireworks" on the talent show and are planning on bringing back Nicole Scherzinger as a judge, The Sun reports.
The popstar pair fell out when Williams quit Take That in 1995 but have since made-up when the Angels and Rock DJ singer rejoined his bandmates in 2010 for a new album and string of sell-out concert dates.
A spokesman for the show said: "It's far too early to say anything about the judging panel for this year's X Factor."
The X Factor judge Gary Barlow has said he has closed his music label Future Records because he has too many commitments, including his home life.
All of the artists signed up to the Take That star's Future Records are to be taken over by the label's parent company Universal.
Barlow, whose fourth child, Poppy, was stillborn in August, told The Sun: "It's been a very difficult decision but it came down to time. I've had a lot going on recently and I want to spend more time with my family."
Take That star Gary Barlow said he was "deeply proud" to be awarded his OBE by the Queen.
The 41-year-old X Factor judge, who has spent more than 20 years in the public eye, was given the title for services to the entertainment industry and to charity.
In a statement Barlow said he had been surprised by the award and that it "hadn't seemed real until today".

Robbie Williams has teased fans with the prospect of another reunion with Take That pal Gary Barlow after posting a picture online of the two of them rehearsing.

The photo is accompanied by the caption: "Robbie and the Captain - what are they up to?"
Williams was reunited with his erstwhile bandmate earlier this month when they teamed up as Barlow was celebrated with a Music Industry Trusts Award at a gala dinner.
Both performers are due to play solo shows in the coming days. Williams is on the bill for the Royal Variety Performance on Monday and will play headline shows at London's O2 Arena from Thursday.
X Factor judge Barlow is to perform a Little Noise Sessions show for Mencap on Monday at east London's St John-at-Hackney Church, and is also playing a series of shows throughout this month and through to January as part of his first solo tour for 13 years.
