Mexican superstar Paulina Rubio may be busy judging La Voz Kids on Telemundo, but sources are reporting that she’s in final talks to sign on as an X-Factor judge. E! News reports that sources at Fox Networks are trying to move away from casting megastars like Britney Spears, Nicki Minaj and Mariah Carey in favor of somewhat lesser-known artists who already have experience on similar shows. Also rumored to be joining the judge's table is Kelly Rowland. X-Factor creator and judge Simon Cowell is set to make the announcement soon.
