Simon Cowell and Paula Abdul may be chummy now, but the reality TV judges weren't always friends.
In an interview with Barbara Walters for her "10 Most Fascinating People of 2011" special, Simon says they couldn't even stand each other in their early "American Idol" days.
"The first two seasons, we couldn't travel on the same plane together," he admits. "We really disliked each other that much."
When asked why, the "X Factor" judges says it the sex factor!
"I think it sexual tension ... on her part," Simon explains.
"Paula Abdul wanted you?" Barbara poses.
"A million percent," he laughs. "I considered it, but then I thought, I don't think the after would be as good as the before."
Just watch Simon's response when asked about "the morning after." Let's just say he's falls into the "love 'em and leave 'em" category!
