Yasmin Le Bon has broken her shoulder falling off a tuk-tuk.
The supermodel was travelling on a motorised rickshaw in central India as she geared up for a 350-mile charity trek, but the vehicle hit a pothole causing her to sustain the injury as she was thrown onto the road.
A source said: "It was quite frightening. The roads aren't quite what we are used to and the tuk-tuk hit a hole and sent them flying out.
"Yasmin was quite badly hurt. She broke her shoulder and was in quite a lot of pain."
The 51-year-old star - who was one of the highest earning models in the 1980s - was taking part in an event called Travels to My Elephant to raise money for the protection of endangered animals with her 26-year-old daughter Amber when the terrifying incident occurred.
However, the disaster - which happened on the second day of the race - brought an end to their efforts even though they raised £25,000.
The source explained: "Amber was OK and came through with barely a scratch.
"Organisers decided that due to the seriousness of the injury it was best for Yasmin to fly home and they had to quit the race."
A spokesperson for Yasmin - who is married to Duran Duran rocker Simon Le Bon - told The Sun on Sunday newspaper: "She is feeling a little bit uncomfortable. It was a shame as it all happened on the second day and they were really looking forward to it."
