The 32-year-old split from first husband Ashley Cole in 2010, following multiple reports of his infidelity.
So it's probably not the best subject to joke about at an audition for The X Factor, when a yes from Cheryl could change your life, is it?
However one hopeful clearly didn't get the memo. The contestant was asked by Cheryl if they had a husband, to which they replied: "No, well not one of my own!"
Understandably the joke didn't go down to well with the former Girls Aloud singer. The Mirror reports that she quipped: "In future, don't make jokes about stealing peoples' husbands!"
In July last year, Cheryl married Jean-Bernard Fernandez-Versini – three months after meeting him at the Cannes Film Festival.
She and JB tied the knot in secret on the island of Mustique, and threw a bash to celebrate with all their family and friends later that month.
Despite the bad joke, Cheryl apparently decided to give the hopeful a chance and put them through anyway.
They must have caught her on a good day…
