Susan Sarandon has warned celebrities they're heading for heartache if they continue to boast about their relationships in the media.
The Dead Man Walking actress, 58, refuses to divulge the secrets of her longrunning romance with actor Tim Robbins - who she's been dating for 17 years - because she fears exposing such intimate details could have disas trous consequences.
Sarandon says: "My formula for a successful relationship is never to talk about a successful formula, because it's bound to go wrong.
"At a certain point you have to decide that you are going to be with this person, and not be looking towards the door to see who else is coming in, in case they're better.
"I don't know when that point comes - maybe it's to do with age, or maybe it's who you're with.
"But you do have to decide to grow with them, and hopefully they will grow with you, too."
