Hollywood actress Uma Thurman has broken "multiple bones" after falling off a horse whilst riding this week, according to New York Post's Page Six.

A rep for the 46-year-old 'Pulp Fiction' actor told the publication she was involved in an "equestrian accident" after the horse became "spooked".

They said: "Uma was in an equestrian accident. She was training on a young thoroughbred who got spooked. She was thrown and broke a few bones".

According to a source, Thurman was later spotted "walking gingerly" into the La Plage restaurant in St. Barts, aided by her children.

They said the actor "looked like she had hip surgery."

She is expected to make a full recovery, according to reports.
