LONDON: Cheryl Cole was left shaken after being bitten on the lip by a deranged girl fan.

The Girls Aloud singer was posing for photos outside her hotel when a teenager lunged at her.

Witnesses said X Factor judge Cheryl, 25, looked “petrified” before a security guard shoved the fan out of the way and whisked the singer into the hotel.

The hysterical fan, who wore a brace on her teeth, ran off shouting: “I kissed Cheryl, I kissed Cheryl” — not realising she had accidentally bitten the beauty.

Moments later Nadine Coyle, 23, stepped off the tour bus ready to chat with fans.

But security swiftly ushered her into the hotel.

A witness said: “Nadine didn’t know what had happened. It had left Cheryl petrified.”

The incident happened as the girl group arrived back at the Malmaison Hotel, Belfast, after a show on their Out Of Control tour at the Odyssey Arena.

About 30 fans were waiting to meet the band. A witness said: “This girl was hysterical and totally obsessed with Cheryl.

“She lunged at her and her brace must have nicked her lip. Cheryl looked absolutely terrified.

“The band’s security manager said Cheryl had been hurt and was shaking.”

The girls were due to stay another night at the hotel but chose to go straight to Dublin instead for their next concert — travelling in blacked-out cars rather than their tour bus.

A Girls Aloud spokeswoman said: “Cheryl was left shaken. As a result the girls have been more cautious greeting fans.”
