Anna Friel has ruled out having any more children until 'Pushing Daisies' has finished.The 31-year-old actress - who has a three-year-old daughter Gracie with partner, actor David Thewlis - wants to expand her family, but is more concerned with continuing her role in the hit US TV show.Anna plays Charlotte Charles, who is bought back to life by her high school sweetheart, but discovers she will die again if she ever touches him. She said: "I definitely want more kids. I'd like another two probably, but not yet. I can't right now - I'm not sure how they would explain my character on 'Pushing Daisies' getting pregnant when her leading man can't actually touch her. What am I - the Virgin Mary?"Anna also said she is not worried about coping with pregnancy in weight-conscious city Los Angeles because the obsession with size is unhealthy.She added: "I don't think being self-obsessed is a very endearing quality to have. Just being self-aware and healthy is enough, I think."
