The 'I Don't Care' singer, 32, was apparently NOT impressed when a wannabe made a comment about married men - and soon got put in her place by the feisty Geordie.
Before a middle-aged duo started their performance at the show's live auditions in Manchester, Cheryl politely asked them if they had husbands.
According to the Mirror, one lady replied: "No, well not one of my own!"
Understandably, Cheryl disliked the comment and reportedly shot back: "In future, don't make jokes about stealing peoples' husbands."
Hmmm, we don't think it was a "yes" from Cheryl!
Cheryl fans know that her first marriage to footballer Ashley Cole ended in divorce because of his infidelity.
While Cheryl has not commented on the report, she DID log on to her Instagram and Twitter accounts on Friday (10 July) to share a HILARIOUS throwback photo with new X Factor judge Nick Grimshaw.
In the snap from 2003, Nick looks very, ahem, different!
In fact, he is barely recognisable.
Wearing rimless glasses and visibly heavier in weight, this is Nick before a serious style transformation and a high profile job at Radio 1!
Bless him, he is only 18 years old in the picture and might not thank Cheryl for sharing it!
She also added a recent photo for comparison, with the message: "Fast forward Friday to Me, The Grim @nicholasgrimshaw and @ritaora's chair bc we missed her yesterday #evolution #2015era."
Nick definitely looks more like himself, with skinny black jeans and leather jacket, while Cheryl is wearing a black and white striped dress.
The singer has been forced to defend her weight loss recently after a troll called her a 'bag of bones'.
