By Jack Guy, CNN(CNN) — Hollywood star Michelle Pfeiffer has announced that she has become a grandmother, and spoken about how it has affected her working life. It’s ridiculous,” said Pfeiffer, 67, who has an adopted daughter Claudia Rose and a son named John Henry. “And if I had known that I was going to be a grandmother, I wouldn’t have taken on so much work, but I’ve enjoyed everything and I’m really grateful,” she said. I’m so grateful because I love acting… in fact, I probably, enjoy it more now than I ever have because I’m sort of more relaxed with it,” said Pfeiffer. “I don’t have the time nor the desire to go that deep for that long and not be present,” said Pfeiffer.
