LOS ANGELES, (Reuters Life!) – Oscar winning actors  Susan Sarandon and Tim Robbins have split up after more than  two decades together, Sarandon’s representative said yesterday.

“Actress Susan Sarandon and her partner of 23 years, actor  Tim Robbins, have announced that they separated over the  summer,” Sarandon’s representative Teal Cannaday said in a  statement.

A representative for Robbins could not immediately be  reached for comment.

The pair were not married, but they have two sons together.  For years, they have been one of the entertainment industry’s  most enduring couples, known for their film work as well as  their social and political activism.

Sarandon stars in “The Lovely Bones,” which was released in  U.S. theaters earlier this month, and she won an Oscar for her  role in the 1995 criminal execution movie “Dead Man Walking.”

Robbins won a best supporting Oscar for his role in 2003’s  “Mystic River.” He also is an author and the director behind  “Dead Man Walking.”
