The 'Run the World' singer will be supported by either Sam Bailey, Luke Friend or Nicholas McDonald when she reaches the UK and Ireland in 2014.
X Factor executive producer Mark Sidaway revealed the news on Twitter, writing: "We just supersized our prize. Winner also gets to join Beyoncé in the UK leg of her world tour."
The 'Mrs Carter Show World Tour' will see Beyoncé play ten concerts in February and March, performing in cities including London, Glasgow, Manchester, Birmingham and Dublin.
This week, Beyoncé released her fifth album, which sold over 80,000 copies in just three hours in the US.
Each of the album's 14 tracks has its own music video and other bonus video content. A physical release is expected before Christmas.
The X Factor Final airs on Saturday and Sunday at 8pm on ITV.
