Cheryl Fernandez-Versini has warned 'X Factor' contestants not to cheat on their partners.
The 'Crazy Stupid Love' singer - whose first marriage to Ashley Cole ended amid reports of his infidelity - advised a group of male auditionees not to give in to temptation as they were being questioned by fellow judge Simon Cowell about whether they had girlfriends.
An audience member at the auditions in Wembley on Saturday August 2 said: "Simon was asking if they were hiding secret girlfriends.
"Cheryl just leapt in and said that if they were they mustn't cheat on their lovers. She left them in no doubt she was deadly serious. It raised a few eyebrows, because everyone knows what Ashley Cole put her through."
Meanwhile, the two judges reportedly spent much of yesterday's auditions squabbling and unable to agree on anything, with Cheryl getting annoyed by Simon constantly interrupting her.
When she asked five guys what made them stand out from other boy bands, Simon objected: "That was a really ridiculous question. They're not a boyband!"
Cheryl protested: "I wasn't talking to you."
The pair continued to bicker, with the former Girls Aloud star eventually telling Simon to shut up and going on to shout: "If he doesn't stop whispering in my ear, I will... Grrrr."
