Cowell and DeGeneres Sure Don't Idolize Each Other

Simon Cowell and Ellen DeGeneres just don't get along.  The tension is building sources from  "American Idol" say.
Apparently, Simon and Ellen aren't even trying to hide it. Ellen can't stand what she believes is Simon's cruelty toward contestants. Sources say, Simon actually enjoys ticking off Ellen with his degrading critiques.
Sources from the show said it was apparent on and off camera.  Simon's tolerance level for the contestants was at an all-time low, and he knew it was making Ellen uncomfortable but clearly didn't care. As one insider put it, "He was intentionally pushing her buttons."  Stay tuned, it's gonna be a long season of "American Idol."
