According to The Hollywood Reporter, Kutcher – aka Demi Moore’s much younger husband -- is getting a “huge payday” to join the hit sitcom.

Show creator Chuck Lorre, who’s in a lawsuit with Sheen after bouncing the star for erratic behavior, has written a storyline to introduce Kutcher to the temporarily-cancelled CBS hit.
