Chris Medina American Idol

Chris Medina, from Oak Forest, Illinois, near Chicago floored the judges with his incredible performance at the Milwaukee auditions, which were screened last night in the first of this week's two shows.

The 26-year old barista from Illinois appeared on Wednesday's tryout episode of the national singing competition, and brought with him his girlfriend, Julia Ramos. She was there for a different kind of inspiration: two weeks before they were to marry, Ramos was in a car accident, leaving her with brain damage.

Now Ramos' caretaker, Medina tried out for the show, bringing Ramos along and introducing her to judges Randy Jackson, Jennifer Lopez and Steven Tyler.

Afterwards Jennifer told her: 'That’s such a beautiful song.' Patterson replies: 'Thank you,' mistaking her remark for a compliment.

But after being set straight, she storms out of the audition room, after insisting: 'I'm not even upset,' and accusing the judges of rejecting her because she is not skinny enough.

Geeky teacher Scott Dangerfield shows you should 'never judge a book by its cover,' in the words of Randy Jackson after singing a tuneful and adept Amos Lee track.

But student Megan Frazier fails to hit the right note as she attempts Justin Bieber's Baby.
