Artist and film director Sam Taylor-Wood is expecting a child with her 19-year-old fiance. The 42-year-old already has two daughters from her marriage to art dealer Jay Jopling. Taylor-Wood began a relationship with actor Aaron Johnson while making the John Lennon biopic Nowhere Boy. Her spokesman said: "We can confirm that Sam is pregnant with her and Aaron`s first child. "Both are very, very happy." He did not say when the baby was due. Last month the London-born artist, who has twice fought cancer, heaped praise on Johnson, calling him "brilliant". "We`d definitely work together again - he`s a brilliant actor," she said. "There was an intensity when he walked through the door. He spoke to me in a Liverpool accent and I knew he wasn`t from Liverpool. He was in character from that moment."
