Cameron Diaz has been promoting “Shrek: Ever After” and recently told People Magazine that Suri Cruise already knows who “Princess Fiona” is. Apparently she was telling them how big a fan Suri is when she stated, “I’m not going to speak for her, but yes, I think she does love Shrek.” Even though Suri knows the real secret on who Fiona is Diaz does ask that parents allow their children to believe in the magic of make believe.
