"I feel sorry about a comment I made about Chemmy and I think I upset her a bit," The Sun quotes Witt as saying. "I said she's a big girl and she misunderstood.
"I meant it in a complimentary way, that she is a tall girl. As a skater I was a big girl, I was tall, I was big. I must say I am sorry. I think it was really a language thing so sorry, sorry Great Britain."

Witt has been backed by the latest Dancing on Ice cast-off Mark Rhodes, who insisted that the judge had been nothing but pleasant during his time on the show.
"She meant powerful. Katarina has not got a bad word to say about anyone, she's a sportswoman saying it to another sportswoman," he stated.
"Sean is a massive unit. Chemmy is built for skiing, she is built for power and that is all she was trying to get across. She apologised to her - it just got lost in translation."
