Amid recent reports that Chris Brown broke up with his current girlfriend, Karrueche Tran, he’s been spotted on Rihanna’s mega-yacht in the French Riviera.  Both, Brown and Rihanna have hinted at a possible make-up through social media over the past few months.  Brown’s rep denies he was with Rihanna. The New York Daily News has the story:

Chris Brown is once again rocking Rihanna’s boat.

A source close to the Barbadian beauty says her troubled ex-boyfriend may not have landed a helicopter on the luxury yacht she’s chartering around the French Riviera, as some are speculating, but that doesn’t mean he hasn’t spent time on it.

According to the insider, Brown boarded RiRi’s 170-foot yacht — named “Latitude” — last week in Sardinia, where the 24-year-old singer temporarily had docked the vessel.

“He was probably there for two days,” says the insider, who saw Brown, 23, firsthand on the island off Italy, but added that “Rihanna doesn’t want anyone to know that they are together.”
