Mariah Carey has reportedly cancelled her tour dates next year because she will be too heavily pregnant to perform.

The pop diva - who recently crossed the pond to appear on the X Factor - will not be exercising her eight-octave range next year because she will be expecting a mini Mimi, according to U.S. reports.

Mariah was recently spotted emerging from the gynaecologists clutching a baby scan picture.

And she also hinted to Hello! that a pregnancy could definitely be on the cards for her and hubby Nick Cannon: "I just think about it as the next phase.

"We’ll see."
