Chris Brown — Singing with Rihanna in Orlando Nightclub

Chris Brown didn”t shy away when the DJ blasted a Rihanna song at an Orlando nightclub this weekend — instead, he proudly sang along with EVERY lyric … and our sources has the footage.

It all went down at Club Vain on Sunday night during an NBA All–Star weekend finale party.

Chris was hanging on the main stage … with everybody looking at him … when Rihanna”s “We Found Love” began to pump through the speakers … and Chris made sure everyone knew he”s a HUGE fan of the song.

It”s the latest in what seems like a public reconciliation between the two sides — earlier this month, the two collaborated on remixes of each other”s songs.
