Reason for their legal action is the second season of \"Rock Star\", the reality series that feature the creation of a new supergroup, also named Supernova.

The Supernova on CBS TV shows Mötley Crüe drummer Tommy Lee (photo) banding together with Voivod/ex-Metallica bassist Jason Newsted and former Guns n\' Roses guitarist Gilby Clarke, trying to find a singer for their new group.

Says bassist Art Mitchell of the Orange County based Supernova:

\"It\'s like when you\'re a little kid and the bully down the street steals something from you and you don\'t do anything about it. But we\'re going to go kick some butt, dude. They probably figured we\'re clerks, but our drummer, Dave [Collins], is a lawyer.\"

Collins claims his group legally owns the name, and they have responded to CBS in the form of a cease-and-desist letter. Continues the bass player:

\"You can\'t just waltz up and use our name. We\'re willing to fight for our name, our band. We have trademark rights to the name and we can prove those rights.\"
