We're sure his heart will go on!

Leonardo DiCaprio and his Victoria's Secret supermodel girlfriend Erin Heatherton have called it quits after nearly a year of dating, a source revealed to Us.

The Great Gatsby star and the blonde bombshell blame their career commitments for the ending of the relationship. "They split a few weeks ago. There's no bad blood - they still care about each other a lot," a source told the mag.

The pair began dating in December of last year, shortly after the A-list actor ended his brief relationship with Blake Lively, but their busy schedules prevented them from spending time together in recent months. "They're both just really busy, they had crazy schedules.They still love and respect each other very much. It was just time to move on," the source adds.
