British pop star Lily Allen is reportedly pregnant with her first child. The Smile hitmaker found out she was expecting Chemical Brothers star Ed Simons' child last month (Nov07), but has only revealed the news to close family members, including her actor father Keith. A source tells British newspaper the Sun, "Lily is thrilled to be pregnant and can't wait to become a mum. She's a real family person. "Ed's very happy. He is really looking after her." The 22-year-old has been dating Simons, 37, since September (07).
