Los Angeles: Ashton Kutcher may have mocked Charlie Sheen on stage at the Emmys, but the former and the current stars of 'Two And A Half Men' bonded behind the scenes.

Sheen, who was replaced by Kutcher on the show, tweeted a photo of him talking intensely to him at the backstage at this years Emmy Awards, the Hollywood Reported said.

"Giving the new kid a little advice," he wrote on Twitter along with the photo.

Earlier on stage, Kutcher said, "I am not Charlie Sheen" before turning to his 'Two and a Half Men' co-star Jon Cryer and saying, "Jon, I want to tell you something. I do not think
that you are a troll."

Sheen infamously called Cryer a troll around the time he was fired from the Warner Bros-CBS show.

For his part, Sheen played it straight on stage earlier.

"Before I present outstanding lead actor in a comedy series... my old category. I want to take a moment to get something off my chest and say a few words to everyone here
from Two and a Half Men...from the bottom of my heart, I wish you nothing but the best for this upcoming season," Sheen said.

Alec Baldwin boycotts Emmy

Actor Alec Baldwin boycotted the awards after the event's broadcaster refused to air a joke he made about the phone-hacking scandal at News of the World.

Baldwin, 53, was to be part of an opening video with reference to phone hacking scam for the ceremony but said he was disappointed when Fox News bosses announced they were selectively editing his opening address, which had been recorded days in advance, according to reports.

The actor immediately asked that his appearance be cut altogether from the show.

In a message on Twitter Baldwin suggested that Fox, which is owned by Rupert Murdoch's News Corp, the parent company of News International, was wrong to take out the joke.

"If I were enmeshed in a scandal where I hacked phones of families of innocent crime victims purely for profit, I'd want that to go away too. I think it would have made them look better. A little," Baldwin tweeted.

A Fox spokeswoman said the reference was removed because News Corporation was taking the hacking allegations "seriously" and did not want to appear to be making jokes about it.

The actor and film director Leonard Nimoy, who played Spock in the original 'Star Trek', was brought in as Baldwin's replacement.
