X Factor wannabe Rachel Lester has been branded the rudest auditionee ever after launching into a stream of abuse against the judges.
According to the Mirror the 25-year-old was so vulgar she had to be forcibly removed from the audition room by security guards.
And Sharon Osbourne described Lester as an “ugly, ugly person”.
“In four years, we’ve never had anyone that abusive come into the room,” she told the paper.
The audition – which will be seen on Saturday night’s show – began with the Cardiff girl comparing herself to Madonna and Prince before launching into her rendition of the Sheena Easton song Sugar Walls.
However things turned nasty when she was criticised by Simon Cowell. “You’ve got a really bad attitude, everything I wouldn’t want,” he told her. “Lazy, deluded, very little talent.”
Lester proceeded to turn the air blue with a tirade of insults and swearing against Cowell and Osbourne, and fellow judges Dannii Minogue and Louis Walsh. She even continued to hurl abuse at them as she was taken from the room.
“She was physically scary and intimidating,” a show insider said. “Sharon and Dannii were frightened.”
