Date: October 6

Mariah Carey kicked off her “Elusive Chanteuse” world tour in Tokyo, and it appears that her ongoing relationship issues with Nick Cannon are still very much a distraction. Rumors about the cause of the couple's split have been swirling since the news broke, but it now looks like Mariah may have called Nick out for cheating during the show.

In the audio from the show, Mariah is heard singing a cover of Billie Holiday's “Don't Explain,” and if you listen closely enough, it sounds pretty clear that Mariah changed an important lyric in the song from, “And I know you cheat, right or wrong, don't matter,” to “I know you cheated, motherfucker.” Earlier this year, TMZ reported that Mariah and Nick had split up and were on a fast track for a divorce, though that hasn't been finalized as of yet. —Zach Frydenlund
