"They split a few weeks ago," a source close to the couple tells Us Weekly. "There's no bad blood -– they still care about each other a lot."

DiCaprio and the Victoria's Secret stunner first stepped out in December of last year, a few months after he and Blake Lively ended their spring and summer romance. At issue in this relationship? "They're both just really busy, they had crazy schedules," the source explains.

Indeed, DiCaprio traveled the globe in 2012, shooting "The Great Gatsby" in Australia, then "Django Unchained" in New Orleans, and then "The Wolf of Wall Street" in New York. "They still love and respect each other very much," the source says. "It was just time to move on."
