Blake Lively, Leonardo DiCaprio Break Up

Blake Lively and Leonardo DiCaprio

Their summer romance is over.

Blake Lively and Leonardo DiCaprio, linked since May at the Cannes Film Festival, are no longer dating, a source close to DiCaprio reveals.

"It's amicable. They're friends," the source says, adding that distance and DiCaprio's work commitments contributed to the breakup.

First spotted together hugging on a yacht on the French Riviera, the pair also clocked time together in Sydney, Australia, zoo, on bikes in New York City and on vacation in Italy over the summer.

Over the weekend, Lively, 24, was spotted in Boston with Ryan Reynolds, according to a report in the Boston Herald. The Gossip Girl star was reportedly spotted on the Acela train and, later, having dinner together at sushi restaurant, O Ya.

DiCaprio, 36, will next appear in J. Edgar, due out in November.
