As if American Idol needs any more fuel for the already astronomical ratings, the producers have announced some very special guest stars. If you tuned in last night for the first eliminations, you saw former American Idol Fantasia Barrino perform. But wait—there’s more! Ryan Seacrest also announced last night that there would be many big name stars showing up as special guests this season. Jennifer Lopez, Gwen Stefani, Jon Bon Jovi, Martina McBride, Diana Ross, Barry Gibb and Lulu and Peter Noone. It’s unclear what the theme will be for each show these performers contribute to, but the star wattage is impressive. Other fun tidbits from Thursday’s program include the announcement that Fantasia will star in The Color Purple on Broadway (with a quick glimpse of producer Quincy Jones), as well as the use of Chris Daughtry’s (another former Idol) song “Home” for the send-off of the eliminated contestants. Another former finalist will show up next Thursday—Kellie Pickler will be on hand to perform her single “I Wonder.”
