The Kanye-Taylor war is officially over!

Before each of their talked-about performances, Kanye West and Taylor Swift secretly met backstage at the MTV Video Music Awards on Sunday, a source tells

"Kanye got word she was going to do the song about him and wanted to talk it out," the insider explains. The duo -- West infamously ambushed Swift onstage at last year's VMAs -- met privately in Swift's dressing room.

"Taylor felt bad. They talked and everything is good between them now," the source continues of their backstage chat. "But they promised to keep what they spoke about between them." No word on whether they hugged it out.

Later that night, a muted Swift referenced their infamous 2009 VMA encounter in her song "Innocent," singing, "You are not what you did."

West closed out the show with "Runaway," rapping, "Let's have a toast for the douchebags."
