Rihanna and Chris Brown — TOGETHER Again … on 2 New Songs

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.
