According to Variety, CBS has greenlit production on a second season of the Mark Burnett-produced talent hunt, Rock Star, which got off to a slow start last summer but ended up a sleeper success for the net. Skein will return this summer, with Dave Navarro and Brooke Burke back as hosts.

Burnett and exec producer David Goffin are keeping a tight lid on details about the new season, saying some key deals have yet to be hammered out.

Original skein was designed to find a new lead singer for Aussie rockers INXS. It's unclear whether the new season will be devoted to finding a lead singer for another headless band or go in a completely different direction, such as creating a new band.

Details on the creative direction could be finalized as soon as this week. Casting has already started, with applications being accepted via CBS.com and Rockstar.msn.com.

Whatever changes are made, "At the end of the day, the show will always be about finding a rock star," Goffin said.

Burnett said it's likely Rock Star will stick with its twice-weekly format on CBS.
