    The award-winning international phenomenon THE X FACTOR is back. In Season Three of the hit competition series hosted by Mario Lopez, THE X FACTOR judges will travel the nation searching for talent 12 years old or over -- both solo artists and vocal groups -- who are willing to brave the panel for a chance to make their dreams of becoming a superstar come true. Auditions for THE X FACTOR were held this spring in Los Angeles, CA; Charleston, SC; New Orleans, LA; Long Island, NY; and Denver, CO.
    Contestants will audition in front of THE X FACTOR judges, including Simon Cowell, Demi Lovato, Kelly Rowland, Paulina Rubio, and an audience of thousands. This will be the ultimate test to prove they have the vocal ability, charisma and stage presence it takes to become a global superstar or breakout music act and win a recording contract with Syco/Sony Music.
    Those contestants who survive the first auditions will be divided into four categories: Boys, Girls, Over 25s and Groups. Each category will be mentored by one of the show's judges. Not only is it a competition between the hopefuls to stake their claim for the coveted win, but it's also a showdown among the judges as to whose acts will dominate the competition and make it to the finals. The judges may have their say in how the competition progresses, but it will be up to America to decide who ultimately has THE X FACTOR.

    I can see why they broke up now after going through Sierra’s (2018) Insta page. She’s completely changed. She doesn’t even look the same. Looks like she got her lips filled and botched up. Sad really.... her and Alex was the best together... idk who she is now :( she seemed so real here and now she seems fake. I was so in love with Alex&Sierra when they were on XFactor kinda sad to see how people change.
