Bieber debuted a sneak peak of his new video for "Boyfriend" and then jumped off stage to greet the judges - Adam Levine, Cee Lo Green, Blake Shelton and Aguilera. After he hugged the blonde starlet, her smile turned into a look of disgust.
When news of her ice cold reaction spread on the internet, Christina tweeted, "Haha! The media loves spinning stories...Can't a girl have a little Bieber Fever after getting kissed by the Biebs?"
What do you think of Christina's reaction?
