Hotel heiress Paris Hilton was taken to hospital after a horse she was riding threw her off and kicked her in the stomach.
The accident occurred during the filming of The Simple Life 2, a reality show featuring Hilton and her friend Nicole Richie on a 30-day cross-country trip.
Hilton, 23, was first treated at the scene in rural Florida north of Tampa, then taken to a hospital, said Chris Alexander, publicist for 20th Century Fox in Los Angeles.
The kick to the stomach left her bruised, but she was not seriously injured, said St Joseph’s Hospital spokeswoman Lisa Patterson. Hilton was released about three hours after she was brought in and was never admitted to the hospital, she said.
Camera crews were taping the socialite-turned-TV star when she was thrown, Ms Alexander said.
The sequel to The Simple Life features Hilton and Richie on a month-long cross-country trip with no money, credit cards, mobile phones or boyfriends.
Hilton and Richie, adopted daughter of singer Lionel Richie, helped make the first season of The Simple Life a huge success for Fox.
The young women supposedly break free from their sheltered upbringings, working odd jobs milking cows and flipping burgers at a fast-food restaurant while living with a family in ultra-rural Altus, Arkansas, population 817.
