Cowell blushes as shirt bursts open
X Factor boss Simon Cowell cringes with embarrassment after his shirt bursts apart, accidentally flashing his chest.
His display of a little too much flesh - and hair - as his button popped open prompted wolf whistles and cheers from members of the audience at the arena audition in scenes to be screened on ITV tonight.
Cowell was seen on the big screen in the venue with his white top gaping as he came to give his verdict on a performance by hopeful Fleur East.
As the whistles and squeals rose, he turned to Cheryl Fernandez-Versini at his side to ask: "What's going on?"
"Oh, my shirt!" he exclaimed, laughing as he realised what had prompted the noise from the audience.
As Fernandez-Versini patted his shoulder reassuringly, Cowell hid his face in his hands, keeping himself hidden while he told East: " I really, really liked that."
"I'm so embarrassed," he admitted shortly afterwards.
Viewers see Fernandez-Versini take a dislike to contestant Rachel Rabin, 31, who uses the stage name Raign and has previously written songs for Rita Ora and had her music included on TV soundtracks.
During a previous audition the judge had made it clear she was not a fan, by telling her fellow panellists: "She's not likeable at all."
And shows her opinion has not changed when Raign - who tells viewers she is "a little bit edgy and I'm also free-spirited and mad and don't really care about how I'm looking" - performs on stage for her Wembley Arena audition.
After winding up the panel and audience with a speech before her performance, she then asks for a microphone stand with Fernandez-Versini responding: "Anything else? Vodka? Gin and tonic?"
The judge looked stony-faced throughout the self-written song Don't Let Me Go - which has previously been released on iTunes - and afterwards tells the panel: " I couldn't stand her. I couldn't work with her - no way. I'm aller gic to her."
The other judges were also irritated by Rabin, with Cowell telling her: "For whatever reason, people don't like you before you sing, I sense that because you do kind of drone on a bit."
Fellow panellist Louis Walsh grumbled: "When you walked down you behaved like a total diva before you sang. I could feel the audience not liking you. You're overconfident."
Cowell continued his criticism by telling her: "The dress was hideous, your eye make-up, everything about you was a bad choice."
Tonight's show also sees a TV return for former Luminites singer Stephanie Nala who previously made it through to the final of Britain's Got Talent in 2013.
The 20-year-old has now gone solo after the quartet split and she performs the Baby D hit Let Me Be Your Fantasy, with Fernandez-Versini declaring: " You've got the sweetest, softest tone to your voice."
