Brown joins Rihanna on vacation
Brown, 23, took a helicopter down Riviera to Saint Tropez, where he boarded a chartered boat, which will be parked close to Rihanna's yacht.
"Chris is staying on the yacht next to Rihanna's. He's got rappers Swizz Beatz and Ludacris with him and they've decided to film a music video too," The Sun quoted a source as saying.
"It was a last-minute trip, but Chris wanted to see Rihanna. They have this weird addiction to each other and can't seem to stay away," the source added.
Brown and Rihanna parted ways in 2009 after she complained of physical assault.
