Mariah Carey kicked off her Elusive Chanteuse Show tour in Japan on Saturday (Oct. 5). According to various reports, the veteran songbird suffered some highs and lows during her performance at Tokyo's Makuhari Messe Arena.

The entertainer performed over 20 classic songs from her catalog including her No. 1 songs and new material from her latest effort, 'Me. I Am Mariah...the Elusive Chanteuse.'

MC went through four wardrobe changes and showed off photos of Dem Babies -- Monroe and Moroccan.

But things got a little rocky on a few songs during her show. In videos circulating on the Internet, it appears that Mimi was having some vocal problems with a number of tunes.

When Carey was performing 'Always Be My Baby,' she had trouble hitting the high notes. On 'We Belong Together,' Carey forgot the lyrics altogether after her microphone stand broke and she had to start over. Finally, during her performance of 'My All,' the singer was, um, a little pitchy.

While all of these blunders are a little troubling, we have to say that this is Mariah Carey's first major tour outing in quite some time. Mishaps often happen on the first night of a major tour -- nothing is ever going to run smoothly. So, hopefully, Carey and her team can fix some of these problems as the trek continues throughout Asia this month.

Meanwhile, Carey may have put her soon-to-be ex-husband Nick Cannon on blast during the concert as well. According to reports, while the singer performed a rendition of the Billie Holiday classic 'Don't Explain,' she added a few new words of her own to the original song.

After singing the original lyrics, "Cry to hear folks chatter / And I know you cheat / Right or wrong, don’t matter / When you’re with me, sweet," she then adds, "I know you cheated motherf---er."

Since Mimi and Cannon are going through a rough patch in their marriage, is this a subliminal shot at her estranged hubby?
