Diana recaps "Rock Night" for OK! Magazine

For the second week, Diana recapped the performances for the eighth season of American Idol. With only four finalists left in the competition, things heated up when they sang songs from the rock catalog and a few pre-show mishaps provided for a scare that caused the audience to evacuate the studio temporarily.

This week, Diana attended the show and was a member of the live studio audience, sitting behind Slash, who served as the contestants' mentor for the week. Below is an excerpt of what was on Diana's mind this week:

For the first time in Idol history, the contestants had to sing duets and, honestly, I don't think it was Idol's brightest idea.

Danny Gokey and Kris Allen sang Styx's "Renegade" — a kick-butt song — and sounded fabulous together, but how in the world were the judges supposed to judge THAT?? Songs for the show can barely be a minute and a half and then when you have to divide that again with another contestant — huh, what, why??

The arrangement done for Kris and Danny didn't give enough "personal shine time" for either of them. That was just plain unfair. The judges gave the guys a hard time, but I was jamming out with them the whole song!

Diana seemed happy with her trip back to the Idol studio, even mentioning that she received a wave from judge Simon Cowell. She had positive things to say about each contestants' performances, commenting that Adam Lambert's "confidence was very obvious from the moment he stepped out on that stage" and how Allison Iraheta "picked a perfect song for her voice."
