CBS entertainment chairman Nina Tassler made the announcement during the network's press briefing ahead of its presentation to advertisers, reported Los Angeles Times.
"Chuck Lorre is creating a season-long event. Chuck is very psyched about this. He's got some great ideas and very big surprises," Tassler said.
The comedy drew blockbuster numbers back when Charlie Sheen was a key player in the sitcom.
The series, despite losing steam, is still a strong performer. Its most recent season averaged 9.1 million total viewers, with 2.3 million adults under 50.
But events behind the scenes overshadowed achievements in the ratings arena. The controversy surrounding Sheen's antics on set, his feud with creator Lorre and his 2011 firing fuelled countless headlines.
Ashton Kutcher was recruited to fill one-half of the man-void, starring opposite original cast member Jon Cryer.
Then there was the fuss surrounding former cast member Angus T Jones, who badmouthed the comedy and its message. Jones, who later apologised, went from regular to recurring.
His last episode was in May 2013.
'Two and a Half Men's end gives Lorre a bit of respite. The TV maker has three other series on the network: ratings juggernaut 'The Big Bang Theory', 'Mike and Molly' and recent entry 'Mom'.
