Strictly Come Dancing contestant, Ali Bastian, has been performing without realising that she had torn a ligament.

The Bill actress told The Sun that was sure she had only sprained her ankle, but the injury turned out to be more serious than that.

Bastian said: “I sprained my ankle three or four days into training and I have been dancing on it the whole time.

“I didn’t want to make a big deal of it, but now I have found out I have got a little tear in the ligament.”

She added: “But I’m looking after it, icing it, doing all the right things and they have strapped it up for me. I’m trying to pretend it’s not there but it’s painful.

“I really need to have it up for a few days but that’s not going to happen. I’m so focused and loving what I’m doing that I don’t want anything to stop me in my tracks.”
