In 2002, Jane's Addiction again reunited and recorded a studio album, with Chris Chaney now playing bass. Following the release of
Strays in 2003, Jane's Addiction went on a massive worldwide tour, which included an American tour as part of
Lollapalooza 2003, which was only moderately successful. After the tour was completed, Navarro, Chaney, and Perkins posted a message on Navarro's site announcing that Jane's Addiction had broken up yet again, saying that "Sometimes the best creative relationships are the most combustible and they aren't meant to last forever".
In 2004, Navarro contributed his guitar ability on
Dead Celebrity Status' debut album,
Blood Music. He played guitar on their lead single, "We Fall, We Fall." Also in 2004, Navarro contributed his guitar work to
Glenn Hughes's album
Soul Mover. He also performed additional guitar on
Flyleaf's self-titled album in
2005.
In 2005, Navarro began serving as co-host of the
reality TV show
Rock Star: INXS, alongside
Brooke Burke. During the competition to determine a new lead vocalist for
INXS, the exposure and success of the show made Navarro's name much better known among mainstream music fans. Navarro returned to work on a new season of
Rock Star called
Rock Star: Supernova, which premiered in North America on
July 5, 2006 and ended on
September 13, 2006. They are forming the band
Supernova which features
Gilby Clarke (ex-
Guns N' Roses) on guitar,
Jason Newsted (ex-
Metallica) on bass and
Tommy Lee from
Mötley Crüe on drums with the lead singer,
Lukas Rossi, having been selected at the end of the show's run. On the final episode, he committed to working with
Rockstar: Supernova Runner-up
Dilana on her upcoming album.
In 2006, he focused his energies on his new band,
The Panic Channel, which is made up of himself,
Stephen Perkins and
Chris Chaney of
Jane's Addiction, and lead singer
Steve Isaacs. He also has started an Internet radio station called Spread Radio Live, where he hosts non-FCC regulated radio via the internet along with other hosts such as Electra,
Messy Stench, and the
SuicideGirls' Bee Jellyfish.
On
May 17, 2007, the hourlong, weekly "Spread Entertainment" debuted on Navarro's website. Navarro said he was attracted to doing a show on the Internet because of the lack of censorship. Navarro said that "I want to use the Internet to support artists and see things that are out there that other corporate structures aren't allowing us to see. It seems with satellite TV, the Internet, magazines -- there's almost so many options, and we're only seeing the same five things."
