After two years of retirement, during which she stood by her manager-husband, René Angelil, during his health crisis and had a baby, born just over a year ago, Celine Dion is ready to return to the working world. Speaking to Barbara Walters in a "20/20" interview that aired Friday, the 33-year-old music superstar unveiled a new song, "A New Day Has Come," and talked about her life, which includes fulfilling a reportedly $100-million contract headlining at Caesar's Palace in Las Vegas starting next year. The break, she told Walters, was because "I needed to stop. I needed a balance in my life. I wanted a normal life at one point. I wanted to be home . . . I've never had a normal life," she said from her palatial Florida home. Speaking of her baby -- the Angelils's son, René-Charles, who was conceived through in vitro fertilization -- Dion said that he "is the extension of the love (René and I) have for each other ... René-Charles is everything that we have accomplished together." Yet just before she was pregnant, Angelil, who is 26 years his wife's senior, was diagnosed with throat cancer. "René needed me with what he's been through, and I felt good about it. I can do something good, not only through music, but I can be a woman at home. I can be his wife. I can make a difference in his life." She also put to rest tabloid stories that Angelil lost some $10 million while gambling. "The truth is, it's not true. He's a gambler, but he's smarter." And his gambling doesn't bother her, she insisted. "I'm glad he is," she said, "because he mortgaged his house to make me do my first album when I was 12 years old. That's probably the biggest gamble he's ever done."
