Simon Cowell missed X Factor auditions because he had a migraine

Los Angeles  - Simon Cowell missed X Factor auditions.

The 54-year-old music mogul missed the afternoon session at London's Wembley Arena with a migraine, prompting fellow judge Cheryl Fernandez-Versini - who he argued with several times during try-outs over the weekend - to joke she was pleased he was away as he had been giving her a headache throughout the auditions.

According to the Daily Star newspaper, she told the crowd: "A migraine? He's been giving us a migraine all week.

"At least it means less rudeness if he isn't here."

While Simon and Cheryl have been squabbling, they have also had some fun as the day before, the Crazy Stupid Love singer and fellow judge Mel B did a lap dance for the head judge during a contestant's rendition of Marvin Gaye's Let's Get It On.

Afterwards Simon said: "I think we both had a good time during that song."

It was revealed on Monday that auditions at the weekend had been blighted by squabbling between the judges, 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."
