First Van Morrison slags off The Beatles, and now Trent Reznor is laying into Chris Cornell. Only Reznor is doing it the hip, hi-tech way, using Twitter to slam the former Soundgarden/Audioslave singer.

"You know that feeling you get when somebody embarrasses themselves so badly YOU feel uncomfortable? Heard Chris Cornell's record? Jesus," Reznor wrote, coming just 4 numbers shy of Twitter's 140-character rule.

The previous Reznor entry reads: "And, I'm not wearing any pants." (In case you were curious.)

Cornell stays mum...for now.
