Chris Brown was seen kissing former girlfriend Rihanna while each of them was on a vacation in St. Tropez, France. They were seen kissing each other openly while they were partying on a Malaysian businessman’s yacht, according to the New York Daily News.

Rihanna’s friends and fans are worried as they wonder whether Rihanna’s getting back together with Chris Brown is a good idea, given the stars' heated relationship. Chris Brown's assault of Rihanna in 2009 not only sparked uproar among her fans but also led him to plead guilty to a felony charge in the case that resulted in a sentence of community labor, domestic-violence counseling, and probation.

The news of Rihanna and Chris Brown getting together sparked a lot of reactions by their fans via social media.

Some took it with a pinch of humor, as Dirt Nasty/Mr. RexVerified ‏@DirtNasty tweeted: "So Chris Brown and Rihanna are rumored to be back together and recording some songs? Ill bet they make a 'hit.'"

And others failed to see the humor in the situation, as High Class HoodRat ‏@ihate2minaj tweeted: "Chris Brown beat poor Rihanna like that & he thinks we are going to support him? RETWEET if you DIDN'T buy Fistophor's album!"

Whether the latest rumors of Chris Brown's and Rihanna’s rekindled romance are true or not, this certainly is a heated love story. Meanwhile, little is known about how Chris Brown's current girlfriend, Karrueche Tran, is dealing with these new rumors about her boyfriend.
