Joe Jonas Was ‘Honest’ As ‘American Idol’ Guest Judge, Nick Says

'Having that balance of giving your honest opinion but giving some constructive criticism is important,' Nick Jonas says.

Joe Jonas is the latest celebrity to sit at the judges’ table with Simon Cowell, Randy Jackson and Kara DioGuardi before Ellen DeGeneres joins the “American Idol” crew for Hollywood Week. Jonas joins other superstars like Katy Perry , Shania Twain and Mary J. Blige as celebrities who helped fill the void during the audition process.

Younger brother Nick said Joe enjoyed himself while taking in the Dallas tryouts in the fall. “We talked about it, and he had a great time,” Nick told MTV News. “He said that he was nice, but he also was honest, and that’s important.”

Joe told Nick that the “Idol” crew found some really good talent in Texas. “He said he found some really great people that he’s looking forward to see what their journeys are going to be like,” he said. “And I’m happy that he was able to do that.”

Nick took some time to judge Joe’s abilities as a judge and said he seemed to combine the styles of Simon, Randy and Kara. “I think he’s a mixture of all three,” Nick said. “And I think that having that balance of giving your honest opinion but giving some constructive criticism is important.”
