AMC has already announced plans for a third season of Mad Men.

But that's actually news to creator Matt Weiner, who is not signed on to continue with the series. He talked to E! at the Golden Globe Awards last night.

"I don't know anything about next season - I don't even know if it's happening," Weiner said, adding that the show's fate right now is "unknowable."

What's the hold up? Weiner said he's done everything he can during recent negotiations.

"I don't even know what to tell you. I don't know what to say… I've done everything I can. That's all I can tell you."

Despite the stalemate, AMC president Charlie Collier announcedlast week that Mad Men will return this summer for a third season... with or without Weiner.

"Lionsgate [TV] continues to be in negotiations with Matt, so I won't go too deep into an active negotiation," Collier said. "But we remain optimistic that Matt will be part of the show, and third quarter has always been our plan" for the season three premiere.
