Professor Green and Danny O'Donoghue: Don't take the piss out of Cher Lloyd!
The Swagger Jagger singer, 19, walked off stage following the incident and was seen crying before returning to finish her set.
‘chin up @cherlloyd xx'
And The Script frontman Danny O'Donoghue, 32, told Gigwise, ‘That's an awful thing to happen to such a young girl, and I hope she doesn't take offence from it.
‘I would probably have said the organisers could have seen that before it happened.'
Even stars who previously slagged off X Factor protégée Cher have stuck up for her, including rapper Example, who once got into a row with Cher's after slating her debut single.
‘Whilst i'm not a fan of Cher Lloyd I don't think anyone deserves bottles of piss thrown at them.,' Example, 30, told his Twitter followers.
‘Stick to plain old booing in future people'
