News: 'She can't sing anymore': Fans mock Mariah Carey's vocals as she kicks off Tokyo tour

Mariah Carey has been criticised for her vocal performance following a concert in Japan on Saturday.

As the 44-year-old singer kicked off her Elusive Chanteuse World Tour in Tokyo last night, but it seems her energetic set didn't go down too well with some fans.

One Twitter user, Elle, wrote: 'It's a wrap for Mariah Carey's singing career. You're a legend. Time to retire. She can't sing anymore. At all. What happened?'

A user, who goes by handle Peaches & Herb, tweeted after seeing the video: ‘Y'all. Mariah Carey really can't sing anymore. That was hard to listen to.

‘I see why Mariah Carey never sings live anymore. That's why.’

She added: ‘Mariah Carey should've bowed out right when her voice was giving out. Save herself the embarrassment.

‘I knew it was something wrong with MC though. No artist lip syncs at EVERY show.’

The Hero hitmaker also appeared to struggle with her microphone when singing We Belong Together, with the butterfly decal detaching from the mic.

She attempted to continue uninterrupted with the song, though halted saying, 'Wait a minute. I can't go on.' 

However, it seems some fans thoroughly enjoyed themselves, with Abby tweeting: 'I just had the absolute best time at @MariahCarey.

'#TheElusiveChanteuseShow #Tokyo Def a night to remember!!!!'

Me.I am Jevi tweeted: 'A+mazing! And can't believe there were 23 songs! Looking forward seeing you at MY & SG!'

A representative for the star claims they've only received good reviews from people who attended the opening show.

A spokesperson said: ‘The comments we have heard from the fans have been great!’

Mariah's performance comes just weeks after she split from her husband Nick Cannon, whom she married in 2008 and has three-year-old twins Moroccan and Monroe with.

The mother-of-two will tour through Asia in the month of October before heading to Australia and New Zealand.
