TWITTER KING ASHTON Kutcher gave his followers a big clue yesterday that he may be joining “Two and a Half Men” — either that or he’s punking them.

This was his Tweet yesterday:

The answer is 2.5.

Kutcher’s online message came amid reports that he’s nearing a deal to replace the fired Charlie Sheen on TV’s top-rated comedy. The 33-year-old was negotiating with series producer Warner Brothers, the LA Times is reporting, citing unidentified sources.

Warner Bros declined comment, as did CBS. Kutcher’s representatives did not immediately respond to a request for comment.

There is deadline pressure to get a deal done, with CBS presenting its fall lineup to advertisers in New York next Wednesday.

It’s been more than two months since Warner fired Sheen in the show’s eighth season, a move that followed the hard-living actor’s bouts of wild partying, repeated hospitalizations and a bitter media campaign against his studio bosses who shut down production. Since then, Sheen has performed a one-man stage show called My Violent Torpedo of Truth (Defeat is Not an Option), looked to hire an intern with ‘Tigerblood’, and said he would sue Warner Bros for $100 million.
