Chris Brown and Rihanna: Together again in the Mediterranean?

Rihanna and Chris Brown have traveled some rough seas in the past, first together, then very much apart. But have the two singers been canoodling on a boat in the South of France?

Here’s what we know: Rihanna has been on an extended vacation with girlfriends, first indulging a retail-heavy stint on Sardinia, an island off the coast of Italy.

From there the gang drifted to the French region of the Mediterranean, where she relaxed and partied on her rented yacht with the likes of Magic Johnson in St. Tropez, the Daily Mail said. Chris Brown conveniently touched down on a boat himself, also in St. Tropez, where he’s in town to film a music video with rapper Ludacris.

Brown reportedly joined Rihanna in Sardinia, according to the New York Daily News, prior to joining Luda for the video shoot.

“He was probably there for two days,” the newspaper said, claiming an eyewitness had seen Brown present with Rihanna’s group, adding, “[She] doesn’t want anyone to know that they are together.”

For good reason: The two have faced endless criticism for remaining friendly, even working together, since Brown assaulted RiRi ahead of the 2009 Grammy Awards and earned a felony conviction for it.

Sardinia or not, Brown’s current presence in France is strictly business, his rep said. “There is no Rihanna connection,” the spokesperson told Hollyscoop, adding that Breezy’s girlfriend, Karrueche Tran, is in tow.

Complicating matters: Rihanna’s delirious and profane (you’ve been warned) Twitter feed. All vacation long she’s been sending brooding shots of herself in repose to her “baby” or “boo.”

Not to mention Sunday, when Brown landed in St. Tropez via helicopter, Rihanna tweeted, “Touch down baby, help me pick out my fit,” presumably referring to her ensemble.

No matter their relationship status, these two still know how to make waves.
