Neil Patrick Harris is your latest 'American Idol' guest judge
Harris, who also hosted the Tony Awards this year, sat in with the "American Idol" judges Tuesday during a round of auditions in Dallas, E! Online notes. He's the eighth person to fill the seat vacated by Paula Abdul during the auditions for next season -- and the first without any serious ties to the music business.
Which is not to say he knows nothing about singing: Harris has performed in "Rent" and "Sweeney Todd," among other stage work, and played the title character in Joss Whedon's online sensation "Dr. Horrible's Sing-Along Blog."
Harris joins a guest-judge roster that also includes Victoria Beckham, Katy Perry, Kelly Clarkson and Joe Jonas.
