This is all rumor and conjecture still, nothing official from Bravo yet, but now we're hearing that Marcel Vigneron, Richard Blais, Fabio Viviani, and via Grub Street, Carla Hall are also in Top Chef All-Stars.
According to one tipster, "this is a full season and not a one-off special." Also, this is a spoiler to the current season: The series is to give past contestants who didn't win a second chance at the title.
If all these rumors are true, Top Chef All-Stars (or "Fameballs" as one commenter put it) is gonna be a wild and freaky ride. Here's the list so far:
Rumored Top Chef All-Star Contestants
Marcel Vigneron, Richard Blais, Fabio Viviani, Stephen Asprinio, Angelo Sosa, Carla Hall, Tiffany Derry, Spike Mendelsohn, Michael Isabella, Dale Talde, Tiffani Faison, Jamie Lauren, Antonia Lofaso, Jennifer Carroll, Andrew D'Ambrosi. And more!
