    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.

    this version of toxic is very similar to the cover that Melanie Martinez did on the voice the year before, the way they stop in certain places and the places they go higher and sing a certain way. it’s like the only thing different is the music but even that’s really similar

    From Cher Loylld to Alex and Sierra, you failed because you didn’t follow SimonCowell ‘s advices. His first success is recoding No.1 single and rescued/jumped start his career. Too bad you failed to see his talent behind the brutally honest comments..

    Baby, can’t you see
    I’m calling
    A guy like you
    Should wear a warning
    It’s dangerous
    I’m fallin’
    There’s no escape
    I can’t wait
    I need a hit
    Baby, give me it
    You’re dangerous
    I’m lovin’ it
    Too high
    Can’t come down
    Losing my head
    Spinning ‘round and ‘round
    Do you feel me now?
    With a taste of your lips I’m on a ride
    You're toxic I'm slipping under
    With a taste of a poison paradise
    I’m addicted to you
    Don’t you know that you’re toxic
    And I love what you do
    Don’t you know that you’re toxic
    It’s getting late
    To give you up
    I took a sip
    From my devil's cup
    It’s taking over me
    Too high
    Can’t come down
    It’s in the air
    And it’s all around
    Can you feel me now
    With a taste of your lips I’m on a ride
    You're toxic I'm slipping under
    With a taste of a poison paradise
    I’m addicted to you
    Don’t you know that you’re toxic
    And I love what you do
    Don’t you know that you’re toxic
    Don't you know that you're toxic
    With a taste of your lips I'm on a ride
    You're toxic I'm slipping under
    With a taste of a poison paradise
    I'm addicted to you
    Don't you know that you're toxic
    Intoxicate me now
    With your lovin' now
    I think I'm ready now
    I think I'm ready now
    Intoxicate me now
    With your lovin' now
    I think I'm ready now

    Jedna pani z jury mówi, że wzruszyła się i wierzy w nich, bo mają świetne głosy, które współgrają i że inspiruje ją, iż "trzymają się za ręce". Ów fakt ją inspiruje i daje nadzieję... Takie komentarze są dowodem na upadek i zidiocenie tzw. zachodniej cywilizacji. Wstyd.

    Isn't it sad how six years can change love. It's quite obvious to me that Alex enjoyed the way Sierra looked up to him and Sierra fed off of his strength. When she found her own strength, she no longer needed him and he was disappointed that she no longer idolised him. Life is quirky.

    It's mad that this has so many more views than the original cover of this song by Melanie Martinez that they copied. They sound great, but Melanie was the one with the creativity to sing it like this originally - the link to the original if anyone's interested
