As the "American Idol" auditions continue making their way around the country, we've seen celebrity guest judges like Mary J. Blige and Shania Twain helping Simon Cowell, Randy Jackson and Kara DioGuardi find the next big thing.

On Tuesday night (January 26), [artist id="3274550"]Katy Perry[/artist] and [artist id="1228637"]Avril Lavigne[/artist] sat in on [article id="1630557"]the Los Angeles auditions[/article]. We caught up with Perry after the audition episodes were taped to see how her guest-judging stint went.

"I make 'em cry all the time," Perry joked to MTV News. "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."

Perry said she didn't actually cause anyone to tear up, but she did have a great time during the experience. "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."

Judging the audition rounds is the easy part, Perry said. She's just glad she doesn't have to make the really tough decisions during Hollywood Week and beyond. "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."
