Ciara in wheelchair after injuring ankles?

R&B star Ciara has sprained both of her ankles while practising a new dance move in high heels, according to reports.

The Like A Boy hitmaker raised concerns for her wellbeing after she turned up to the Roll Over Hunger charity event in Atlanta, Georgia on Wednesday (23Nov11) in a wheelchair wearing orthopaedic boots on both feet.

Ciara, who is known for her energetic dance routines, failed to provide a reason for the medical shoes, but according to MediaTakeOut.com, the singer fell awkwardly after jumping in the air in four-inch heels.

But Ciara refused to let the injuries dampen her holiday spirit - she took to her Twitter.com blog on Thursday (24Nov11) to wish her fans a happy Thanksgiving.

She wrote, "Its (sic) all about doing whatever you can to make a difference! Tonight was a GREAT night! LOVE. Happy Turkey Day to ALL!"
