Paula: Simon's Like An 'Antagonistic Brother' | Paula Abdul, Simon Cowell
Their back-and-forth bickering might make for great American Idol drama, but Paula Abdul and Simon Cowell are really friends off screen. At least that's what she tells TV Guide in a recent interview.

Abdul says that their ribbing – and her on-camera grimacing – is just for show. "We have cultivated a fun relationship .... He's actually become a really good friend," says Abdul.

But she adds that Cowell's troublemaking tendencies can cause some problems. "In the middle of me trying to figure out how I'm going to say something that gives someone dignity walking off that stage, I've got the antagonistic brother goofing on me, trying to throw me off," she says in the interview.

Still, Abdul is clear about one thing: Don't mistake her friendly repartee with flirting. "Oh, puh-leez!," she says, when asked about rumors of a possible romance. "He said, 'Paula, people want us to hook up so bad.' I said, 'That's disgusting.' He goes, 'Paula, I know you want me,' and I go, 'Like a cold sore.' "

She adds, spoken like a sister, "We have fun playing up the chemistry, but there's also times when I would cross the other side of the street so I wouldn't have to look at him."
