Rihanna and Chris Brown have reconciled ... at least professionally ... because the former couple have collaborated on 2 brand new songs.
It's only been 3 years since Brown pummeled Rihanna's face during a late night argument in L.A. ... but the singer and her ex-con ex-BF have each released songs featuring the other's voice. One is a remix of Rihanna's song, "Birthday Cake" and the other is a new version of Chris Brown's, "Turn Up the Music (below)."
Both songs hit the Internet this week ... and both Rihanna and Brown have been pushing the songs on Twitter.
The songs seem to prove the rumors ... that Rihanna has forgiven Brown and is willing to move on. Earlier this week, Brown tweeted Rihanna "Happy Birthday" ... and Rihanna actually responded, "Thanks."
Rihanna is currently in London (see photo above) ... and Chris Brown was most recently seen in Miami.
As we previously reported, Brown is currently in a relationship with a woman named Karrueche Tran ... and we're told the two seem very happy together.
