Mariah Carey's husband Nick Cannon thinks the international songstress should record a duet with American Idol rival Nicki Minaj.

Carey and Minaj joined the coveted reality show's judging panel this year alongside Keith Urban and returning mentor Randy Jackson.

Despite the show's new format being in its infancy, it has been rocked by reports of a feud between its new female judges.

Carey's husband Cannon thinks the pair should collaborate to finally put an end to their differences.

He told E! News: "They could definitely do that. Why not? People love that stuff. I'm pretty sure they could figure that out."

Cannon is looking forward to the season premiere in January and hopes that viewers see a different side to his wife - who is largely labelled one of music's biggest divas.

He gushed: "I think it's all about the opportunity for people to see Mariah for who she really is. You'll get to see how intelligent she is… how witty, and her great sense of humour. Also, her nurturing spirit and wanting to help all these young people accomplish their dreams."
