Fox in Cannes: Bar Refaeli Trying to Make Leo DiCaprio Jealous?

Leonardo DiCaprio’s ex, Israeli model Bar Refaeli, has been making a concerted effort to make the actor jealous this week at the Cannes Film Festival.

The pair were reported to have split last week, yet they are both in France this week— DiCaprio spending time with director Steven Spielberg and attending charity dinners with Sean Penn, while Refaeli has been hitting red carpets and fashion events with George Clooney’s girlfriend.

Earlier this week DiCaprio, who has a history with sexy young blondes, was snapped getting close with “Gossip Girl” actress Blake Lively, 23, on a private yacht. The pair were spending some down time in between films with Spielberg and his wife Kate Capshaw.

But either the rumblings are untrue or the pair aren’t ready to go public just yet. DiCaprio, 36, told reporters and photographers at the Cinema for Peace dinner honoring Sean Penn at the Carlton Hotel on Wednesday night that he and the much younger actress were only friends.

Elsewhere in town Wednesday evening, at the Roberto Cavalli party celebrating the opening of the designer’s new boutique in Cannes, Refaeli, 25, hammed it up for the cameras in a nude beaded mini dress by the designer, partying with George Clooney’s Italian girlfriend Elisabetta Canalis. The ladies sipped champagne and got down on the dance floor with a gaggle of Refaeli’s model girlfriends. One model pal tells Fox411 that Refaeli kept an eye for Leo all night and made sure she was photographed having a good time in the hopes of making her ex beau jealous.

“It is a little desperate,” she told us.

DiCaprio and Refaeli have been dating on and off for about six years following the actor’s split from his other longtime girlfriend, supermodel Gisele Bundchen.

There were whisperings that the two had reconciled here in Cannes, but those have been put to a rest as they hit the town with their respective entourages rather than one another. The model also pranced the red carpet solo for the Cannes premiere of the Mel Gibson flick “The Beaver” earlier this week.
