'American Idol' Guest Judge Katy Perry Didn't 'Make Anybody Cry'

'But I did tell the truth to some kids that might have needed to hear it,' singer says.

[artist id="1962774"]Katy Perry[/artist] tried to strike a balance between sympathetic and critical when she sat in as a guest judge for the "American Idol" auditions in Los Angeles. So, how tough was she on the contestants?

"I make 'em cry all the time," she joked to MTV News during a set visit for the video of her duet with 3OH!3, "Starstrukk." "The 'American Idol' experience was awesome. If I was offered that job as a permanent host I would ditch my career and take on that career."

But Perry admits that maybe it was only fun because, well, it's not her real job. Having the gig permanently would probably turn up the heat quite a bit. "I guess the pressure gets really on when you start eliminating the number of people that are going through," she said. "Ten, nine, eight, seven, six, and then you've got the final two. That can be kind of tense and stressful."

The experience gave the singer a newfound respect for the tough decisions Simon Cowell, Kara DioGuardi, Randy Jackson and newbie Ellen DeGeneres will have to make, but she said that sitting at the judges' table for a day is a lot of fun for an "Idol" fan. "It's kind of like judging a talent show," she said. " 'American Idol' was great fun. It was so easy. I didn't really make anybody cry, but I did tell the truth to some kids that might have needed to hear it."
