Amal Clooney's sister and George Clooney's sister-in-law has been sentenced to three weeks behind bars and given a fine for drink-driving in Singapore.

Tala Alamuddin Le Tallec, 47, pleaded guilty on Monday to driving offenses including drink-driving, using a car without a Singapore Class 3 driving licence and driving without insurance.

The sister of the international human rights lawyer, who is a permanent resident of Singapore, has been ordered to pay a fine of S$6,400 (£3,640) and will be disqualified from driving for four years after her release from prison.

She had been driving her husband's BMW X5 at the time of her arrest and he may also be liable for the offences as the owner of the vehicle under the Road Traffic Act, the Straits Times reported.

Le Tallec had been at a restaurant with a friend in Dempsey Road and had drunk two glasses of wine and a glass of champagne, a court heard.

She was driving home with the friend in the front passenger seat at around 2.30am when she was stopped by police along Holland Road towards Ulu Pandan.

Staff Sergeant Alvin Lee noticed that Le Tallec appeared to struggle to locate the vehicle's handbrake and that she smelled of alcohol.

Upon reaching for her bag in the rear passenger seat to retrieve her driving license, Le Tallec reportedly hit the accelerator briefly by accident.

She was then given a breath test by the officer which proved she was over the legal limit, and was arrested.

Le Tallec's lawyer, Mr Shashi Nathan, said his client was 'genuinely remorseful', according to the publication.

Le Tallec owns her own fashion line, Totally Tala, and relocated to Singapore from New York City after marrying a businessman.

She reportedly has a previous driving conviction in Singapore, dating back to 2013.
