Last week, John Stamos shot down rumors that he was in talks to replace Charlie Sheen on 'Two and a Half Men.' But those rumors have rekindled, and there might be some more truth to them this time.

According to E! Online, CBS chief Les Moonves chatted with Stamos on Saturday about possibly joining the network's hit sitcom.

"They were at the bar talking, and Les asked John if he'd be interested in replacing Charlie," a source told E! "It wouldn't be to play Charlie's character, but they talked more about introducing a new character."

On Friday, though, Stamos tweeted, "Contrary to the rumors, I am not replacing Charlie Sheen on 'Two and a Half Men.' However, Martin Sheen has asked me to be his son."
