EXCLUSIVE: Leonardo DiCaprio Dating 'Sports Illustrated' Model Nina Agdal

While this is the first pic of the couple's PDA, sources tell ET they have been dating for the past two months.

According to a source, a relationship blossomed between the pair after DiCaprio invited Agdal to the Cannes Film Festival in May.

"Leo invited Nina to Cannes and she hung out with him and his friends," the source told ET. "Leo definitely courted Nina in the beginning. She wanted to make sure she wasn't just another one of his models. They're really happy and having a lot of fun together."

The two have been spotted at several of the same events since the festival, but the notoriously private DiCaprio previously avoided being photographed with the Denmark native. The couple was spotted at Up and Down nightclub in May -- along with Rihanna -- but weren't caught in the same frame there either.
