Sharon Osbourne attacks Susan Boyle in radio rant

TV judge Sharon says Susan Boyle 'got hit with the ugly stick'

In an apparently unprovoked attack, Sharon Osbourne has launched a foul-mouthed tirade on Britain's Got Talent runner-up Susan Boyle.

The America's Got Talent judge tore into the Scottish singer in an interview on US radio, telling listeners Boyle looks like 'a slapped a***'.

Speaking about Boyle's success, Osbourne giggled: 'I like everybody to do well. Even somebody that looks like a slapped a***. God bless her.'

To add further insult to injury, the 58-year-old claimed Boyle was a 'lovely lady' who needed 'a Gillette razor', making a scathing reference to Boyle's facial hair.

'It's like, "You go girl,' she said. 'She does look like a hairy a***hole.'

She continued: 'He [God] gave her the talent. Yes he did. [And] he hit her with the f***ing ugly stick.'

The outburst comes after Osbourne made a public display of her support for Boyle by blowing her a kiss as she performed live on America's Got Talent. She was also reported to have calmed Boyle's nerves before she took to the stage.

So why the vicious attack? To see Sharon in action, watch video footage from the interview below.
