Earlier this week, The X Factor UK's judging lineup was revealed via the show's official Twitter feed, with Take That's Gary Barlow, Destiny's Child singer Kelly Rowland, N-Dubz's Tulisa Contostavlos and returning participant Louis Walsh sharing a panel in the first series not to feature Simon Cowell as a regular judge.
Tonight, a message was posted on the show's micro-blogging account, confirming that the I'm A Celebrity presenter and former X Factor finalist will helm ITV2's companion show, after former presenter Konnie Huq was axed earlier this year.
The message read: "@carolineflack1 and Olly Murs @ollyofficial confirmed as hosts on Xtra Factor! #xfactor (sic)"
Flack, who had originally ruled herself out of the role on the show because of her presenting job on I'm A Celebrity, took to her Twitter account to thank her fans for their messages of support.
"Thankyou all so much..en route to Birmingham now for first auditions...xx," she wrote.
"It does mean I'm sadly leaving the jungle. But had two fab years with the best team and only have incredible memories!! Xxxxx"
This year's first X Factor auditions begin in Birmingham tomorrow.
