CBS chief executive described the future of crisis-ridden sitcom Two And A Half Men as uncertain as troubled star Charlie Sheen spoke of a drug-free life with two "goddess" girlfriends at his home dubbed Sober Valley Lodge.
Leslie Moonves said he hoped the top-rated TV comedy would return, adding: "We'll see."
Sheen's personal woes and public tirades against producers of Two And A Half Men reduced the show's season.
But Mr Moonves said CBS was not suffering financially in the short term because paying for fewer-than-planned episodes of the expensive sitcom was "financially a gainer".
"Going down the road ... I don't know what's going to happen," he said, then hit out at Sheen's ongoing media tour.
"He's on the air quite a bit these days. I wish he would have worked this hard to promote himself for an Emmy."
Sheen (45) has been nominated four times for lead actor in a comedy series for Two And A Half Men, but has never won.
Meanwhile, Sheen was a guest on Howard Stern's radio show discussing his career as a Hollywood playboy, after a return to NBC's Today.
Asked about reaction to previous comments in which he called himself "a total rock star from Mars" among other startling descriptions, Sheen shrugged off the reaction.
"I am grandiose because I live a grandiose life. I'm tired of being 'aw shucks'. That's not me. ... What's wrong with that?"
Sheen had high praise for the two women living with him whom he calls "goddesses".
"These women don't judge me. ... They don't lead with opinion. They don't lead with their own needs all the time," he said.
Sheen insisted he was no longer using drugs, saying "drug tests don't lie" and presenting recent test results with "the word 'negative' is, like, printed, like, 18 trillion times".
He has rejected attempts by his family, including his father, The West Wing and Apocalypse Now star Martin Sheen, to intervene in his life and told them: "I appreciate your love and your compassion, if that's what you want to call it.
"I'm not interested in people treating me like a 12-year-old."
Sheen joined Twitter yesterday, a day after his publicist, Stan Rosenfield, resigned and had attracted more than 160,000 followers by early today.
The first message he posted was a photo of himself and porn star Bree Olson smiling and holding up a bottle of chocolate milk and a fruit drink. It was subtitled: "Winning! Choose your vice."
Sheen has left open the possibility for reconciliation with most of those he has attacked in recent days, but when it comes to getting Two And A Half Men back on the air, he has made clear he wants it on his terms.
"I'm just going to keep pressing the truth, " he told Today.
