Trent Reznor (Nine Inch Nails) working with Jane's Addiction?

According to Chart Attack Nine Inch Nails frontmamn Trent Reznor has been posting photos over the last few days in a photo blog on the bands website.

Labelled "a look at something else that's been going on," the photos show Reznor in the studio with Jane's Addiction guitarist Dave Navarro, drummer Stephen Perkins and bassist Eric Avery.

Reznor has been posting updates on what's believed to be his Twitter account, including a hint on Jan. 26 that he's "up to something cool I'll tell you about soon." On Jan. 28, he wrote, "In the studio. Not with NIN." The original Jane's Addiction lineup, which also includes singer Perry Farrell, performed last year for the first time since 1991. The band will perform again soon in Los Angeles, according to their website. 

Jane's Addiction have also created an "In The Studio" blog section on the site, but nothing has been posted on it yet. It seems Reznor is still bitter with Radiohead. Nine Inch Nails recently lost to the British band at the Grammy Awards in the best boxed or special limited edition package category. Reznor wrote in a Feb. 8 Twitter post: "Ghosts DESTROYS In Rainbows deluxe package. No debate."
