Kutcher, who plays dimwit slacker Michael Kelso on the Fox sitcom, has inked a new deal taking him through 2005 and upping his per-episode fee to the $250,000-$300,000 range -- or about $8 million for a full season, according to The Hollywood Reporter.
Kutcher was already signed for the 2003-04 season. But show producer Carsey-Werner-Manda- bach pulled a coup by keeping him around for another year since he's one of Hollywood's hottest, most-talked-about talents - and could have bolted for greener pastures.
In addition to his much-publicized romance with Moore, Kutcher produces and stars in MTV's Punk'd - in which he pulls pranks on his celebrity friends - and is set to star on the big screen in The Dinner Party with Bernie Mac.
The readers of People magazine recently voted him "The World's Hottest Bachelor" - barely edging out Prince William.
Kutcher has starred on That '70s Show since its 1998 premiere along with Laura Prepon, Topher Grace, Danny Masterson, Wilmer Valderrama and Mila Kunis.
