Jelena Jankovic at Cannes Film Festival for amFAR benefit gala

Let's not forget that Jelena Jankovic is a movie star herself.

Remember her documentary movie, Jelena's World?

Jelena took some time off from her Roland Garros preparation and attended the amfAR's Cinema Against AIDS 2009 gala at the Hotel du Cap in Antibes, France, during the annual Cannes Film Festival.

The lovely dress Jelena was wearing was designed by Georges Hobeika.

Bad hair day? Love her dress but Jelena needs to fire her hairstylist.

The event was attended by many celebrities included Sharon Stone, Robert Pattison, Annie Lennox, etc.

Here, Jelena shared some light moment on stage with kungfu star/Bond girl Michelle Yeoh.

The tennis star seemed a lot tougher as if she could take Michelle down anytime with just one hand.
