The British supermodel threw an extravagant party in Jodhpur, India to celebrate Vladislav Doronin turning 50, and asked the Motown legend to perform for guests including Kate Moss and Demi Moore.
Ross was seen using a wheelchair at Lax airport in Los Angeles after the event, sparking fears for her health, and her representative has now confirmed the star fell over and broke her ankle after singing at the event.
The spokesperson says, "Ms Ross accidentally slipped and broke her ankle at the end of a show in India in November.
"She is fine and has been recovering. She will be performing next week for the President in Washington, D.C."
