Sting's singer daughter has spent four days in an intensive care ward after fracturing her skull when she collapsed in a restaurant.
Coco Sumner, 18, was dining with a friend in Los Angeles when she complained that she was feeling unwell.
When she tried to stand up, she collapsed, knocking her head on a chair as she fell to the ground.
She was taken to hospital where a scan showed she had a fracture to her skull.
Sting, 57, who is working in the US, rushed to be at her bedside when she called him after the accident, which happened last weekend.
Coco’s mother, actress Trudie Styler, flew to Los Angeles to be with her daughter.
A source told The Mail on Sunday last night: ‘Coco went flying and landed with a real crash. She really took a tumble.
‘One of the waiters helped her to her feet but she complained that she didn’t feel well.
‘The staff and Coco’s friend were very concerned and called for an ambulance and Coco was taken to hospital. No one was taking any chances as it was quite a scary fall.
‘She hadn’t had anything to drink and it happened quite early into the evening.’
The source added: ‘The doctors are still running tests. Obviously it’s a serious injury and Coco is under constant surveillance.’
A friend told The Mail on Sunday: ‘Trudie and Sting were obviously besides themselves with worry. It was a blessing that Sting was in the States at the time and was able to get to the hospital so quickly.
‘Coco is still very shaken but she is planning to come back to the UK very soon.’
Coco has a six-figure record deal with Island Records and was in the States working on her debut album.
A family friend said: ‘Sting and Trudie are very proud of Coco and think it’s great that she has inherited their creative gene. Obviously, they were concerned that in order to make music she would be travelling the world at such a young age – but they are very liberal-minded when it comes to rearing their children.
‘That said, they are also very protective and Coco has to call home every day while she’s away to check in.
‘She’s a real daddy’s girl and very close to Sting. He keeps a close eye on her. When she called to say there had been an accident there was panic all round. He dropped everything he was doing and rushed straight to the hospital.
‘Coco still has some work to do – but she will be coming back to the UK soon.’
Friends close to Coco, who plans to release her album later this year, say she intends to put the finishing touches to it before she returns to Britain.
A spokesman said last night: ‘It was a worrying time for Sting and Trudie but, thankfully, Coco is recovering well.’
