(FROM VARIETY) – Fox has ordered six hourlong episodes of a new variety show hosted by Ozzy, Sharon, Jack, and Kelly Osbourne from American Idol producers FremantleMedia North America. A Fox exec says the show will be in the same vein of Sonny and Cher and Donny and Marie, featuring musical performances (some by the Osbournes themselves), comedy sketches, and a gameshow. A Fremantle exec says some segments will include Ozzy ''skewering pop culture,'' while others will ''tap into the sibling rivalry'' between 23-year-old Kelly and 22-year-old Jack. Producers are aiming to launch the series with a Christmas special. (Variety)
