Well, that was fast: Barely a day after Vulture broke the news that Fox was mulling an all-alumni panel of judges for American Idol, with Jennifer Hudson among the names being discussed, there may already be some movement on that front. There's buzz around Hollywood that Hudson and Fox may have already started talks about her joining the show; one source tells us the deal is essentially "done." As always, Fox won't comment. And buzz even from people familiar with the situation does not always lead to deals, as we noted yesterday. But the idea of Idol alumni as judges may not be a dream after all.
