The couple were the subject of a National Enquirer report, in which a friend of the couple claimed that Carey is dead set against having any more children.
"Nick desperately wants to expand their family and has been pushing Mariah to get pregnant... Mariah told Nick her career is her baby right now," the supposed insider insisted.
Carey's spokesperson has now officially denied those claims to Gossip Cop, calling rumours of a rift "ridiculous".
The 'Triumphant' singer gave birth to her and Cannon's twins Moroccan and Monroe in April 2011.
Carey more recently signed on as the latest American Idol judge for a reported $17 million (£11 million) salary.
Cannon has praised his wife's American Idol hiring, saying that she will be "amazing" on the Fox series.
