Mariah Carey is getting some backup from her husband Nick Cannon.

The "America's Got Talent" judge appeared on Los Angeles' KTLA TV on Monday, defending Mariah's take on the much-talked-about feud with Nicki Minaj.  Cannon said that as an outsider, he feels "Idol" has been "perpetuating" the rivalry for their benefit and hinted that his wife wasn't at all happy about it.  Cannon says "She didn't sign up for that." 

He suggested that Mariah has been disappointed with the way things went this season and that she had "foreseen" it when Nicki was first brought on as a judge.  Cannon also raised doubts about Mariah's returning to "Idol," saying she might take another look at it if producers can "get it stable."  

Cannon also appeared on CBS' "The Talk" on Monday where he declared that his wife's time on the Fox reality series would be "a footnote" in her career as a whole.
