No sooner than PAUL ABDUL & SIMON COWELL reunite for new "X Factor" talent show then war is declared!

The Hollywood Reporter, the chronicler of all things Tinsel Town, says that while Paula should be “riding high” after the singer turned reality star snared a cool multimillion dollar deal to reunite with old pal/freneemy Simon, GUESS WHO who isn’t happy?

Paul’s reps at United talent Agency.

The ten-percenters are now locked in a heated dispute with Abdul over commissions arising from her new gig as "X-Factor" judge.

According to sources close to the situation, Paula is refusing to pay the standard 10% agency commission on her X Factor deal, which and allowed Abdul to join Cowell on stage in Los Angeles for the start of judging.

Paula has claimed that the commissions are not owed due to a prearranging prior relationship with X-Factor producer Simon Cowell.

And now her position has led to preemptive legal salvos fired in what may be a very expensive legal battle and  could very well cost Paula her job, insiders say.
