Kutcher tweets Sheen show hint

Twitter king Ashton Kutcher has given his followers a big clue that he may be joining 'Two And A Half Men'.

“What’s the square root of 6.25?” the actor asked in a tweet. The answer is 2-1/2.

Kutcher’s online message came amid reports that he was nearing a deal to replace sacked Charlie Sheen on TV’s top-rated comedy.

The 33-year-old was negotiating with series producer Warner Bros, The Hollywood Reporter said, citing unidentified sources. Earlier, Broadcasting & Cable reported Kutcher had emerged as a candidate for the CBS series.

Warner Bros declined to 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 autumn line-up to advertisers in New York next Wednesday.

Kutcher gained fame on another sitcom, 'That 70s Show', then focused on film roles – the romantic comedy 'No Strings Attached' is the most recent – and producing, including the prank show 'Punk’d'.

Warner and CBS have been shopping for a name actor who could keep the highly-lucrative sitcom afloat without Sheen.

Within recent days, negotiations with Hugh Grant fell apart because of reported creative differences.

There was speculation on Wednesday that Kutcher could parlay his nearly 6.7 million Twitter followers and even bigger Facebook fan club into continued healthy viewership for 'Two And A Half Men'.

But Kutcher’s effort to use social media to boost 'The Beautiful Life', which he produced for the CW network, proved lacklustre – the 2009 series, a venture between CBS and Warner Bros, was cancelled after just two episodes.

It has 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 hospital admissions and a bitter media campaign against his studio bosses who shut down production.
