Simon Cowell loves pissing off Ellen DeGeneres. According to mega news site TMZ, "American Idol" judge Simon Cowell apparently gets some sort of kick out of pissing off new judge, Ellen DeGeneres and word on the street is that they can't stand one another. If you've noticed in recent airings of the show, Ellen no longer sits next to Simon and everytime Ellen gives her critique on a contestant, Simon can usually be found rolling his eyes.

The insider says that the two just flat out don't get along and the tension continues to build. The insider goes on to say that the two don't even attempt to hide their dislikes from one another. Ellen can't stand Simon's cruel comments aimed at the contestants and Simon absolutely loves pissing her off with his blistering critiques. Of course, the insider says had Simon not shown up late to Ellen's first week's taping of Fox's hit reality series, there's a good chance the two would get along.
