Keith Urban Sings ‘Baby, It’s Cold Outside’ With Contestant on ‘American Idol’
Fifteen-year-old Isabelle Parell skipped school to attend the Chicago auditions, and she came in holding a note, on which she had written the first two lines of the song. When she asked Urban to join her, he complied, providing the counterpoint male parts until the third line, where he humorously sang that he didn't know the lyrics because they weren't written there.
Urban said he loved her voice, adding, "I'm not sure about your choice of singing partners."
Randy Jackson was less certain, and he voted against the girl, but the other three sent her through to Hollywood.
