When it came to finding a unique approach to making an "American Idol" audition unforgettable, Isabelle Parell used both her voice and her prowess rather than plastic costumes and props on Season 12's second episode. Upon entering the judge's chambers, the 15-year-old -- who admitted to skipping school in order to make the audition -- came armed with lyrics that she offered to Keith Urban, as she asked him to join her in singing the classic Christmas duet, "Baby, It's Cold Outside." (Watch the audition below.)

"I grew up listening to country music," Isabelle admitted to the camera before meeting the panel. "Keith Urban would be the judge that I'm most excited to see. He's married to one of my favorite actresses, so I'm really excited about that."

Original "Idol" judge Randy Jackson was the first to spot the lyrics in the high school student's hand, asking if it was a report card. Not missing a beat, Isabelle responded, "It kind of is, except it's one of yours."

"Come on, baby," Keith said, accepting the Indiana resident's offer.

After the pair's duet, Mariah Carey and Nicki Minaj were keen to send Isabelle to Hollywood, as was her partner in rhyme, leaving Randy as the sole holdout, without explanation. However, majority wins, and Isabelle is moving on to the next part of the competition.
