And now they've thrown some love in the mix!
If you look at Chris Brown's favorite tweets today, you can see that there is one tweet in there ― from none other than Rihanna.
She tweeted, "Sometimes it feels like we find love in most hopeless place" on Saturday, and of all the tweets ever tweeted, that is Chris' ONE and ONLY favorite tweet.
In the past, Rihanna defended her Twitter friendship with Chris by saying "It's f*ckin' twitter. Not the altar, calm down."
Since the domestic violence incident between the two back in 2009 and Rihanna's restraining order against Chris being lifted earlier this year, we've seen numerous reach outs from both parties via the social network Twitter.
When Rihanna's single "What's My Name" dropped, Chris tweeted that the song was “dope."
When his fanbase #TeamBreezy and her Rihanna #Navy had a twitter dispute, Chris tweeted “Y’all starting to sound extremely childish! #teambreezy and #rihannanavy It’s pointless. Love team breezy & thank you rihannanavy for supporting ya girl.”
Chris has also tweeted @rihanna a couple of times since then, reassuring their followers that there are no hard feelings.
Chris Brown and Rihanna make it clear that they're cool and obviously they still care about each other, but the the real question is, will Rihanna and Chris Brown get back together in the future?
Some people may say they should just remain "friends," but what do you all think?
