and Bar Refaeli
have reportedly split up.
The 'Inception' star and the Israeli-born supermodel - who have been dating
for over five years - ended their relationship
last week after they both realised neither of them are ready to settle down.
A source told the New York Post newspaper: "It was amicable, they're still friends and they are still talking. They just grew apart and went their separate ways.
"Neither are ready to settle down, and both have busy careers that have been taking them in different directions."
This is not the first time Leonardo and 25-year-old Bar have called time on their relationship, they split for six months in 2009 after dating for four years before reuniting last year.
Leonardo, 36, has previously admitted he is unsure if he will ever marry because seeing other people's failed unions has put him off tying the knot.
He explained: "I don't know whether I'll ever get married. I've seen too many supposedly happy marriages go down. I've been as shocked as anyone.
"No one can look at the marriages of other people and make a judgement. I don't know the private lives o the actors I work with. I just know if they are good actors or good directors."
