It's official—Celine Dion is pregnant again. The singer, 41, who had expressed a wish to expand her family with husband René Angélil, 67, announced the news Monday. "Celine and René are very happy," Dion's representative said. "They are crazy in love over the news... they are overjoyed." Dion, herself from a family of 14, conceived with the help of fertility doctors in New York. She and Angélil already have one child together, René-Charles, 8, who was conceived by in vitro fertilization after six years of attempts. Angélil has three other children from previous marriages. Since Dion's concert tour ended in March, the singer has been taking time off to focus on raising a family. Her pregnancy could potentially delay her planned return to the Las Vegas show scene in fall 2010.
