Liz Hurley wants to have two more children. The 'Austin Powers' actress - who already has a four-year-old son Damian from her relationship with movie producer Steve Bing - is desperate to extend her family after she marries her Indian fiancé Arun Nayar in March next year. Liz, 41, has already chosen the names of her next two siblings - Fred and Daphne - after Damian insisted they be named after his favourite characters from the cartoon 'Scooby Doo'. She told Marie Claire magazine: "Damian is obsessed with me having another child. He wants a girl named Daphne and a boy called Fred. He talks about it every day, saying, 'Mommy, when are you putting Daphne in the school next door to mine, will Fred grow into my clothes?" The 'Bedazzled' actress says she and Arun have often spoke about having children but want to wait until they are officially man and wife. She added: "We'll make an effort after the wedding. Not before, I'm too vain."
