Madonna's Bon Voyage

Madonna is hittin' the Cannes Film Festival in high style. Diane Von Furstenberg is throwing her lunch aboard EOS, her husband Barry Diller's $200 million yacht

Is Madonna going to get swept away again?

A source at the Cannes Film Festival says that famed wrap-dress fashion designer Diane Von Furstenberg is hosting an exclusive VIP luncheon tomorrow to toast the Cannes screening of I Am Because We Are, Madonna’s documentary about Malawi AIDS orphans.

The fete will take place aboard EOS, the $200 million 300-foot yacht owned by Von Furstenberg's husband Barry Diller. And guests shouldn’t be late. “Launches will be waiting at 1:30 p.m. SHARP,” the invite reads.

The following night, Madonna joins Sharon Stone as cohost of the annual fundraising fete for AIDS organization amfAR.
