Lukas Rossi has got himself a band. Whether that band is Supernova or not is another matter.

While the 29-year-old Toronto native was the last performer standing after Wednesday night's Rock Star: Supernova finale, it turns out that Tommy Lee, Jason Newsted and Gilby Clarke are going to have to come up with a different name for their band before they can give their new lead singer a taste of the rock star lifestyle.

Responding to a request filed last month by the Orange County-based punk trio Supernova, a federal court issued a preliminary injunction Tuesday against Lee, Newsted, Clarke, CBS and Mark Burnett Productions, prohibiting them from using the name Supernova to tour, promote, sell or record their music.

The injunction request was part of a trademark infringement lawsuit filed in July by the original Supernova--bassist Art Mitchell, drummer Dave Collins and guitarist Jodey Lawrence. Lee, Newsted and Clarke were dropped as defendants from the lawsuit last month.

San Diego-based U.S. District Court Judge John Houston ruled Tuesday that, although the petitioners had not performed or recorded for quite some time, Mitchell, Collins and Lawrence apparently did not "intend" to abandon their rights to their band's name and image. The group formed in 1989 and is probably most famous for its addition to the Clerks soundtrack in 1994, "Chewbacca." The O.C. rockers have also gone by the name of Supernova from Cynot3 at times. (That may have just been during Star Trek conventions, though.)

"This is sweet justice," (original) Supernova attorney John Mizhir Jr. said. "The band members have worked hard for the past 17 years to establish the name Supernova, and they are entitled to continue to perform without any other parties--large or small--infringing on their rights."

Rock Star's producers argued that they purchased the rights to Supernova from another party who held a registered federal trademark.

Mark Burnett Productions' attorney, Gary Hecker, said that he didn't expect the ruling to affect Rock Star: Supernova's new creation from touring or releasing their upcoming album.

So, according to a press release issued Thursday, the band will now go by the name of Rock Star: Supernova. Who knows how they came up with that one.

The injunction certainly didn't affect the season-ending festivities. Rossi, he of the glittery eyelids and black nail polish, wowed his future band mates and judge Dave Navarro Tuesday night with his toughened-up version of Coldplay's "Fix You," and then again with a stripped-down, acoustic version of his own creation, the moody "Headspin."

"For the whole season I've wondered if you could carry a show for two hours," Navarro said after Rossi had completed his final performance yesterday. "And not only can you do it, I'd buy a ticket to see you do it."

Perhaps to see how it's done on the hard-rock side of the business, Paula Abdul was in the audience, where she gave Rossi a standing ovation.

"When Paula Abdul wants to hear great singing, she comes to Rock Star: Supernova," Navarro said, also giving an "I love you" shout-out to the American Idol judge.

While ex-Guns N' Roses guitarist Clarke called Rossi "fearless," Lee offered the highest of praise.

"Cool as hell," the Mötley Crüe drummer said.

Joining Rossi in the final four were Magni Ásgeirsson from Reykjavik, Iceland; Toby Rand from Melbourne, Australia; and Dilana Robichaux, who was born and raised in South Africa but now lives in Houston.

Although early poll numbers Tuesday showed Dilana, with her multicolored tresses and raspy pipes, in the lead, Rossi may have had no need to fret, despite his third-place status at the end of last night's show.

An "inside source" over at Rock Star told E! Online TV columnist Kristin Veitch that the band has "loved him all along and that Tommy Lee in particular has been so over the top in his praise of Lukas during the show that his comments had to be edited out before the episode aired, in order to make it less obvious that Lukas would win."

Magni started out Wednesday at the bottom of the pack, and his rendition of Jimi Hendrix's "Fire" couldn't save him from being the evening's first elimination. Fellow bottom dweller Toby got the crowd going with Billy Idol's "White Wedding" and made it into the show's second half-hour, where he sang the Killers' "Somebody Told Me." Dilana added to the night's fierce-factor, growling out the Cranberries' "Zombie."

Dilana didn't walk away empty handed, either. Awed by more than her triple chin pierce, Navarro invited the 34-year-old to jam with the show's House Band on the upcoming Rock Star Tour and also asked if he could play on her first album, which Clarke offered to help write and produce. (It wasn't the first time a rejectee has been embraced by the band: Navarro, Lee, Clarke and Newsted previously offered to record with fifth-place finisher, Storm Large, while Burnett has offered to produce an album with six-placer Ryan Star.)

But it was the Rossi Posse (kind of like the Soul Patrol, only with more spiked cuffs--seriously, were they handing them out at the door?) that was able to declare victory Wednesday when their boy came out on top after serenading his rabid fans with his take on the Verve's "Bitter Sweet Symphony."

"Lukas, you're our boy, welcome," Lee told his new frontman. Then Lee tore off his shirt and the new band (whatever it's called) brought the house down with the original tune "Be Yourself."

Rossi heads out on tour with Lee & Co. on Dec. 31, when the quartet will headline a New Year's Eve blowout at The Joint in Las Vegas. Their first album is due out Nov. 21.

The Panic Channel, Navarro's new band with Skycycle's Steve Isaacs and fellow former Jane's Addiction members Chris Chaney and Stephen Perkins will do the opening-act honors on the upcoming tour, which will also be joined by several Rock Star castoffs and the show's House Band.
