Simon has confirmed that PAULA ABDUL and MARIAH CAREY are on his shortlist to join him on the judging panel. Other names on his list include NICOLE SCHERZINGER from the PUSSYCAT DOLLS and GEORGE MICHAEL. Here's what Simon had to say about Paula: Quote, "I've spoken to Paula . . . we've taken it down to a smaller group of [candidates] and she is in that group. But you know, it's more than me who makes the decision." (Earlier this week, a "show insider" said JESSICA SIMPSON was one of the "frontrunners" to get a judging spot on "X Factor".)

And here's Simon taking a quick stab at Steven Tyler on The tonight Show.
