CARLSBAD, CA — The hot gossip this morning at the Wall Street Journal's D6 conference: American Idol judge Paula Abdul, seen here in the video for "Dance Like There's No Tomorrow," is in the building. My bet: something to do with Activision CEO Bobby Kotick's appearance, since his company's music game, Guitar Hero, was advertised heavily on the show's final week. Could a new American Idol videogame — one that's not utterly horrible, like the one released last year — be on deck? Update: A tipster inside the ballroom reports:

Lame lame lame Guitar Hero world tour demo ... Paula Abdul is judge

So much for that theory!
