This week new American idol judge Jennifer Lopez starts to see how the job can turn from fun to stressful to tearful. Last week Jennifer showed some aggravation for the first time as some of the contestants flubbed lines and didn’t hit the right notes. Now as we get down to the top 20, grab your tissues before you sit down for Thursday’s episode of “American Idol. According to the rumors Jennifer couldn’t hold back the tears when one contestant had to be eliminated. The hopeful? Chris Medina, the man who stuck by his fiancee after a car accident left her with brain damage. Sources from the “Idol” set said that Jennifer became so overwhelmed by having to deliver the bad news that fellow judges Steven Tyler and Randy Jackson had to talk her through it. Of course any drama is great for ratings.
