VIDEO: No Paula, No Problem: Mary J. Blige Sits in At Atlanta Idol Auditions

Mary J. Blige filled the seat Paula Abdul left vacant on the American Idol judges' panel during the show's Atlanta, Georgia auditions Sunday. The auditions continue in Atlanta Monday.

Idol judge Randy Jackson said Blige's accolades brings credibility to the panel.

"She's one of the greatest to ever grace the microphone, I mean she is a legend in her own," Jackson said. "She's dope. So maybe she can impart some wisdom to these kids because I mean, it's one thing sitting across the table from us, we do it on the regular and everything. But she's out there doing it. She's singing out there every night, performing so they're looking at where they're wanting to go."

In addition to Blige and previous guest judge, Victoria Beckham, producers have confirmed that a third guest judge, 'I Kissed A Girl' singer Katy Perry, will sit in with the panel on the top-rated talent show at some point during the upcoming season.

The eighth season of American Idol kicks off in January on Fox.
