"It's nerve-wracking. It all depends on which celebrities they've signed up and whether you fit in."
Karen also explained she is open to one day being a mum.
The dancer, who is loved-up with opera singer boyfriend David Webb, explained how everything "is falling into place" off screen.
Karen told the newspaper: "Having a baby is a possibility for me. I'm really happy. Everything is falling into place. I adore David. He knows every piece of me and gets me, which is rare. And he likes dogs. I'm probably going to end up with 25."
