Chris Brown and Rihanna vacation and partying on neighboring yachts

It is reported that Chris Brown boarded a private helicopter last night en route to a yacht lounging the seas on the outskirts of St. Tropez, France - the same location where Rihanna is said to currently be vacationing.  

According to music-news.com and numerous other sources, after landing in Nice, France, Brown met up with fellow-rapper Ludacris before embarking on the yacht Le Serene.

While some reports suggest that Brown's current girlfriend Karrueche Tran is along for the trip, others imply that Brown hit the seas solo and his relationship with Tran is currently on the rocks. Some rumors have it they are already official broken-up.

The Barbados-born hip-hop star Rihanna headed to the Mediterranean last week with a few friends following the death of her grandmother. She was seen partying in St. Tropez this past weekend.

Rihanna's own behavior has also been raising some eyebrows, with her tweeting on Twitter "Touch down baby, help me pick out my fit" shorty after Brown confirmed his safe landing aboard Le Serene with his own Twitter update.

Two days ago, Rihanna also tweeted, "Sorry, no phone service in the middle of the ocean! Just Internet! Call you back when I got signal boo! Miss ya."

Suspicious?

Rihanna has been involved in frequent romance drama lately, especially involving a fight which broke out between Brown and hip-hop artist Drake, with insinuations that they were fighting over her. She has also been in the limelight recently for her excessive partying and drinking. Rihanna spending time with Brown just leads to added controversy, given he was charged with violently assaulting her in 2009 which led to their eventual breakup.
