Pop singer Madonna is healing following her horse-riding accident over the weekend, and recuperating at fellow star Gwyneth Paltrow's mansion.The Material Girl was admitted to Southampton Hospital on Long Island in New York on Saturday with minor injuries and bruises after the fall at celebrity photographer Steven Klein's Bridgehampton farm. She was discharged on Saturday night and spent most of Sunday resting at Paltrow's home in nearby Amagansett, according to the New York Daily News. However, the star already appears to be getting back to full health after posing briefly for waiting photographers outside Paltrow's home and insisting she was feeling "better."Madonna's spokesperson Liz Rosenberg is blaming paparazzo Thomas Hinton for Madonna's fall, accusing the photographer of jumping out of the bushes and startling the horse in his attempt to get a picture of the famous singer. Hinton denies the claim, insisting he was on a public road when the incident took place. Rosenberg added in a statement: "Madonna will be having further tests and continues to remain under observation by doctors."
