Not only did she warm the judges’ hearts with her story — she lost 50 pounds since high school — Berkeley student Christina Isabelle impressed them with her singing. 

“Summertime” is always a risky choice, but Christina made it her own. The only note she got? Randy Jackson told the blond belter she needed more confidence!

Will that advice carry Christina Isabelle far? Well, she makes it all the way to the Top 40 but sadly is cut during Vegas Week and does not make the Top 20.

Watch all of Isabelle's performances from American Idol 2013 below.
