The X Factor (U. S. )
Mario Lopez returns to host the third season of this award-winning competition series. Solo artists and vocal groups from across the country audition in front of this year's panel of judges -- Simon Cowell, Demi Lovato, Kelly Rowland and Paulina Rubio -- in hope of proving they have the ability, charisma and stage presence it takes to win the competition. While each judge is responsible for mentoring a group of contestants, it's the viewers at home who cast their votes and ultimately decide who has "The X Factor. "
