The R.I.P. singer, who was linked to the role last week, will act as a temporary panellist as XF bosses are still yet to find a replacement for 2011 judge, Kelly Rowland.
The X Factor confirmed the news on their Twitter account yesterday (27th May), writing: "Or-some news! We can officially reveal that Brit babe and RIP singer Rita Ora will be guest Judging tomorrow in London. #GuestJudgesRule."
This morning, Ora tweeted: "IM HERE...... I CANT BREATHE! X-FACTOR..... IM JUST LIKE YOU REMEMBER THAT. IVE JUST STARTED TOO IM HERE TO HELP!"
Following Ora, it is thought that former Spice Girls star Mel B will guest judge in Manchester this week, with a source telling The Sun: "The guest judges haven’t had a great run so far, but Mel knows the ropes so she should be a hit."
They added: "If it goes well she could be a contender as a permanent judge.”
