Insiders say Nick Cannon is seething with jealousy over his wife Mariah Carey's close friendship with rocker Lenny Kravitz...
From The National Enquirer
"Mariah and Lenny have been friends since they were young," said a source. "They had a crush on one another and all their friends knew it."
Nick blew up when Mariah, 43, posted a picture of herself with the "American Woman" singer on her Twitter page on Aug. 20 with a message urging "Idol" brass to hire him, said the source.
Mariah told Nick to relax because Lenny probably wouldn't even consider doing the show," said the source. But Nick told her,"That's not the point!" I know how you feel about him!"
Mariah assured Nick that she and Lenny are just good friends, but Nick's not so sure."
