The Osbournes are set to return to the small screen as hosts of a new U.S. variety series.

Ozzy, Sharon, Jack and Kelly will host the as-yet-untitled show, which will feature musical performances and comedy sketches - and may even include a segment dubbed The Osbournes Meet the Osbournes, in which the hosts will spend time with another family named Osbourne.

The six-part series, due to launch with a Christmas special, will also see former Black Sabbath frontman Ozzy "skewering pop culture" and will play up the sibling rivalry between 23-year-old Kelly and her brother Jack, 22, reports Daily Variety.

Mike Darnell, Fox Network's President of Alternative Programming, says, "We've been talking about how to renew the variety show concept and make it feel new for years now."

The Osbournes first made names for themselves as a clan with the worldwide success of their 2002 MTV reality show The Osbournes.

Since then, the family has made several ventures into TV presenting, with matriarch Sharon judging America's Got Talent and the first four seasons of British singing competition The X Factor.
