Mariah Carey may have just fired her first shot at Nick Cannon during her sold-out concert at Makuhari Mess in Chiba, Japan Saturday night, Oct. 4, which kicked off her "Elusive Chanteuse" world tour.
The 44-year-old songstress changed the lyrics to Billie Holiday's 1944 track "Don't Explain," causing fans to wonder if Cannon was unfaithful to her amid undying reports that the couple is headed for a divorce.
In an audio clip obtained by TMZ, Carey can be heard singing "I know you cheated, motherf--ker," instead of "And I know you cheat / Right or wrong, don't matter."
A source tells E! News that Carey's plans to divorce from the 33-year-old "America's Got Talent" host are still on track. "She has made up her mind," the tipster said. "She is definitely divorcing him."
In August, Cannon reportedly confirmed that he and the former "American Idol" judge are living apart.
"There is trouble in paradise," he allegedly told The Insider with Yahoo. "We have been living in separate houses for a few months."
He added: "My main focus is my kids," referring to their 3-year-old twins, Moroccan and Monroe, aka "Dem Babies."
In early September, however, Cannon went on a tweet rant, blasting media reports about the split.
"Because my family & I haven't been forthcoming with personal information, people are quick to paint negative pictures and spread rumors," he tweeted.
"For the record I NEVER have, nor will I make a statement regarding my marriage," he wrote in a follow-up tweet.
He even said in one of his tweets that "Trouble in Paradise" is the "dumbest phrase" he have ever heard. "I would never say that sh!t" he added.
Despite all the rumors surrounding their marriage, Cannon also said via Twitter that he will always love Carey "unconditionally."
"What infuriates me most is to hear people slander @MariahCarey . I will forever be in debted to her for blessing me with our children," he wrote on the microblogging site.
"I will always love her unconditionally for this and so much more. @MariahCarey is an amazing Mother and I trust her wholeheartedly, he added, before reiterating, "I love @MariahCarey and that will never change!!!"
In August, Cannon's father, James Cannon, told Page Six that he does not believe that his son cheated on the five-time Grammy-winning recording artist.
"The only thing I can say is that sometimes marriages break down because of cheating or beating, but that's not this case," the father of the record producer said. "Were temptations ever there with other women? Not for Nick, he genuinely loved the married life."
