Madonna is "in great spirits" Wednesday after breaking several bones during a horse-riding accident the previous day, her rep tells PEOPLE.
"Madonna is doing great. She's up and in great spirits. She's not feeling that bad. She's getting around," her publicist Liz Rosenberg says.
On Tuesday – the singer's on her 47th birthday – she cracked three ribs and broke her collarbone and her hand. The injuries occurred during a horse-riding accident at Ashcombe, the entertainer's country estate outside London.
Madonna and an assistant were riding, when the singer, on a new horse she wasn't accustomed to, took a tumble. Her children, Rocco, 5, and Lourdes, 8, were at the home but were not with their mother at the time, Rosenberg said, adding: "The whole family was out in the country, celebrating her birthday."
Madonna's husband, film director Guy Ritchie, took Madonna to an undisclosed hospital, where she was treated and released later that evening.
Madonna reportedly started riding in late spring and is still categorized as a novice.
She has a dance CD due for release this November. It's not anticipated that the spill will prevent her from promoting it, said Rosenberg, who told PEOPLE: "I'm sure she'll be very restless. She's usually doing lots of things at once."
So will she get back on the horse and ride again? "Knowing her, she'll be riding next week," says Rosenberg. "She is a fearless girl."
