Ocean's Twelve star Pitt, 41, and Friends actress Aniston, 35, met in 1998 when they were set up on a dinner date.     

In July 2000 they wed at a lavish ceremony in Malibu.     

In recent weeks, Aniston has been photographed without her diamond wedding ring, sparking fevered speculation that all was not well in the Pitt household.
