A representative for Dave Grohl has struck down speculation that the surviving members of Nirvana plan to reunite and recruit a new frontman.

The band appeared on stage last week for the first time in 20-years where they performed a new song from Grohl's forthcoming documentary Sound City with Beatles’ Paul McCartney.

The one-off reunion ignited speculation that the Nirvana members were planning to regroup. New York Post's Page Six quoted unnamed sources as telling them:

"Grohl has been privately telling friends that he's working on a 'Nirvana anniversary tour with a secret frontman.'"

When the paper reached out to a representative for Dave Grohl for comment about what the sources had told them, the rep called the reported reunion plans "nonsense."

Former Guns N' Roses guitarist Slash will be making a cameo appearance on a future episode of Charlie Sheen's new sitcom, Anger Management.

Slash informed fans via his Twitter page on Monday that he had filmed the spot and he also announced a new recording as well as asked fans to honor the victims of last week's school massacre in Ct. The tweets read "Just did a cameo on Anger Mngmt. Charlie's working w/a great bunch of people of there.

Trying to get back in the swing of things. Still pretty devastated by the events in Newtown last weekend."

Observe a moment of silence this Fri, Dec 21st at 9:30am in memory of the victims of the massacre at Sandy Hook Elementary school."
