Ashton Kutcher says Mila Kunis insisted that they appear on Netflix's 'That '70s Show' spin-off series

• Ashton Kutcher spoke to Esquire about his and Mila Kunis' cameos on the "That '70s Show" spin-off series.
• Kutcher said that Kunis was firm in her stance that they should appear on Netflix's "That '90s Show."

Ashton Kutcher said that Mila Kunis, his wife and costar on "That '70s Show," insisted that they reprise their roles on Netflix's new spin-off series.

"[She] goes, 'You know, we owe our entire careers to this show. It doesn't matter what the script is, we're doing it,'" Kutcher said in a digital-cover story for Esquire, released on Tuesday.

Kutcher and Kunis rose to fame through their roles as Michael Kelso and Jackie Burkhart, respectively, on Fox's hit sitcom "That '70s Show."

The series, which lasted for eight seasons between 1998 and 2006, centered on a group of teens living in Point Place, Wisconsin.

The two stars played on-again, off-again love interests on "That '70s Show" and began dating in real life long after the series concluded. Kutcher and Kunis have been married since 2015 and share two kids.

A spin-off series called "That '90s Show" premiered on Netflix on January 19 and centers on Leia Forman (Callie Haverda), the daughter of "That '70s Show" characters Eric Forman (Topher Grace) and Donna Pinciotti (Laura Prepon).

The 10-episode season features many familiar cast members, including Kutcher and Kunis. During their cameos on the series premiere, Kelso and Jackie reveal that they're back together and getting remarried for the second time. They also have a son named Jay Kelso (Mace Coronel), who becomes Leia's love interest on the show.
