听力原文： Hollywood super couple Brad Pitt and Jennifer Anniston have announced that they are separating. The former couple were married on July 29, 2000 in a lavish Malibu, CA ceremony in front of family, friends and many of Hollywood's elites. The two actors have been extremely busy working on individual projects and have spent a lot of time apart recently as Jen worked on such films as 'Along came Polly' and Brad worked on such films as 'Troy', 'Ocean's Twelve' and the coming 'Mr. and Mrs. Smith. '. They claimed that after seven years together they decided to formally separate and their separation was not the result of any of the speculation reported by the tabloid media and their decision is the result of much thoughtful consideration. They will happily remain committed and ca- ring friends with great love and admiration for one another. What did Brad Pitt and Jennifer Anniston announce to the public?
