The 33-year old actor features in the advertisement with co-stars Jon Cryer and Angus T. Jones, as the three men appear nude, holding up a sign that reads 'All We Be Revealed' with the date of the series premiere underneath.
Kutcher - who is married to actress Demi Moore - was announced as troubled star Charlie Sheen's replacement in May, after Sheen was fired following a public feud with Two And A Half Men creator, Chuck Lorre.
At the time of his public sacking, Charlie told TMZ.com: "This is very good news. They continue to be in breach, like so many whales."
He added: "It is a big day of gladness at the Sober Valley Lodge because now I can take all of the bazillions, never have to look at whatshisc**k again and I never have to put on those silly shirts for as long as this warlock exists in the terrestrial dimension."
Ashton previously described his new role on the show as "the best job in show-business", despite Sheen stating that Two And A Half Men will fail without him.
Two And A Half Men returns on September 19 at 9.30pm on CBS.
