The Bajan singer fuelled speculation that it's all over after she posted an online comment saying "being single sucks".
She later uploaded an image of an empty bed on Tuesday.
But just 24 hours later, Brown posted an image of Rihanna (24) kissing him on the cheek, which was quickly taken down.
This has led to more speculation that all is not well between the pair.
The rumour mill started yet again when Rihanna posted a comment about her life as a single person.
"Being single sucks. The only thing I get to do anymore is whatever the f*** I want to do."
This comment followed a number of cryptic tweets posted over the weekend such as: "Never underestimate a man's ability to make you feel guilty for his mistakes."
And in an online note to her fans, Rihanna wrote about dealing with the "curve balls" that life sends your way and "taking our lessons and growing from them" as well as "keeping it moving without regrets".
Rihanna was unimpressed after seeing her other half party with a bevy of scantily clad girls in Paris before heading on to enjoy a dinner date with his ex-girlfriend Karreuche Tran in Dubai.
Rihanna and Brown originally went their separate ways in 2009 after Brown assaulted the singer.
