Cameron Diaz has ruled out starring in "Shrek the Musical." The actress - who voices Princess Fiona in the animated film franchise - attended the Broadway opening of the musical on Sunday but has no plans to tread the boards herself.

When asked if she would like to play Fiona on stage, Cameron replied: "No. Absolutely not. What they do up there is, to me, impossible. It's wonderful, though. They've done such a great job. They worked really hard, and it really pays off."

Ben Stiller and Christine Taylor, who have two children, are not planning to add to their brood. The "Tropic Thunder" actor is happy raising six-year-old Ella and Quinlin, three, and has revealed he and his wife have no intention of having any more children.

Ben, 42, said: "Our kids are ridiculously cute and every moment is a joy and a wonderful challenge that people who have kids can only understand. It's the best but I'm happy where we're at right now."

Ben Stiller doesn't want his children to watch his films. The "Madagascar: Escape 2 Africa" actor - who has two children, Ella Olivia, six, and three-year-old Quinlin Dempsey with wife Christine Taylor - has banned his brood from seeing anything except his most recent family-friendly films.

Ben, 42, said: "It's great to be able to share with them something they can enjoy. There are not a lot of films of mine I can show to them - but we'll get to them eventually."
