Page Six first reported that the pair have called it quits. The 36-year-old actor and 25-year-old supermodel ended things last week after "going through a rough patch."
The break-up seems to have been fairly drama-free, as the Post's source called the split "amicable" and revealed "they're still friends and they are still talking."
"They just grew apart and went their separate ways," the source said.
DiCaprio and Refaeli -- who have always kept something of a low profile -- got together in 2006 and dated for four years, which was followed by a six month break in 2009. They started up again last year.
The source added: "Neither were ready to settle down, and both have busy careers that have been taking them in different directions."
And, just like that, our hopes of DiCaprio and (newly single) Kate Winslet getting together in real life have been reignited.
