Charlie Sheen on CNN, tells Piers Morgan joking about "being underpaid"

(CBS/AP) LOS ANGELES - Charlie Sheen popped up on CNN's "Piers Morgan Tonight" in a live appearance on Monday - airing opposite "Two and a Half Men" in some time zones - and waffled on whether he was serious about that pay raise.

"I was joking about being underpaid. But to come back for Season 10," he added, looking beyond his current two-year contract, "that's all negotiable. You can't talk about this stuff on television."

Those expecting Sheen to go silent at some point will likely be disappointed.

Warner Bros. Television agreed Monday to pay the crew of "Two and a Half Men" for half of the eight episodes of TV's top-rated comedy that were canceled by producers upset about the off-screen antics of Sheen.

But a Warner Bros. spokesman denied that Sheen's war of words against the studio and series producers prompted the move.

Sheen said he's not concerned with his own sizable paychecks at the moment, which are reportedly worth $1.8 million per episode. "I don't care about me right now," he told the AP.

Sheen's publicist, Stan Rosenfield, resigned shortly after the TMZ interview. Rosenfield has been with Sheen through three hospitalizations in three months related to the star's wild behavior. In the interview, Sheen implied that Rosenfield had lied to the media by saying he had been hospitalized for an allergic reaction after trashing a room in New York's Plaza Hotel.

On ABC, Sheen said to correspondent Andrea Canning that he planned to sue his bosses.

"Wouldn't you?" he said. "I've got a whole family to support and love. People beyond me are relying on that. I'm here to collect. They're going to lose. They're going to lose in a courtroom, so I would recommend that they settle out of court."
