Mariah Carey sings about split from Nick Cannon

Music is all about singing from your heart and singer Mariah Carey bides by the notion as she revealed the reason for the split with husband Nick Cannon during her performance in Japan.

The 44-year-old singer tweaked Billie Holiday’s Don’t explain by adding an angry line, while performing in Tokyo Saturday, reports dailymail.co.uk.

In a recording of the performance posted on YouTube by fan Roy Fernando, the star is seen singing, “I know you cheated motherf***er!”.

Following news of their split in August, Cannon has been linked to a number of women, including actress Amber Rose.

Carey and Cannon, who have three-year-old twins, Moroccan and Monroe, together, got married in 2008.
