Madonna was back on a jet ski yesterday for more fun in the Mediterranean with her kids Mercy and Lourdes, as well as her boyfriend, Brahim. Lourdes Leon was in a bikini for their latest day on the water, just as she was last week, though this time it seemed she had a guy pal there to hang out and jet ski with. Madonna and her crew have moved to the South of France, where they're staying at the Eden Roc Hotel in Antibes, following a stay on the Basque coast. She's due to show off her movie WE at the Toronto Film Festival, but first up will be a stop in Italy. Madonna will also premiere the biopic about Wallis Simpson and Prince Edward on Sept. 1 during the Venice Film Festival.
