Actors Susan Sarandon and Tim Robbins have officially separated after spending over two decades together. Sarandon's rep went on the record, claiming: "Actress Susan Sarandon and her partner of 23 years, actor Tim Robbins have announced that they separated over the summer. No further comments will be made."This news comes as a surprise to many fans, who, while not officially married, had maintained a relationship much longer than would normally be expected for a Hollywood couple. The two began dating in 1998 after meeting while filming Bull Durham. They have two sons together and were well known in recent years for their political activism. No reason for the unexpected split has been given as of now.
