Sarah Harding has been banned from driving for six months and ordered to pay a £500 fine following her arrest earlier this month for driving while using her mobile.
The former Girls Aloud singer pleaded guilty to the charges at Highbury Corner Magistrates' Court on Tuesday, and had her licence revoked, after already having nine points from previous speeding tickets.
Sarah was stopped by police in her 4x4 on 4 April in London's Charing Cross, and was also ordered to pay a £500 fine, a £20 victim surcharge and £85 in prosecution costs at the hearing.
She also faced a charge of failing to stop for the authorities, but it was dropped after her claims it would have been unsafe to do so.
While delivering her verdict, Judge Nina Tempia said of Sarah's lawyer, Nick Freeman: "He is asking the court to deal with you as opposed to a normal person.
"Well, you are a normal person. I can see no reason why you shouldn't be disqualified."
The singer - who was seen outside the court wearing a black trouser suit with a white blouse - only spoke to confirm her name during the 15-minute hearing.
