There are plenty of reasons to watch The Ranch, but at the top of our list is the reunion of Michael Kelso and Steven Hyde -- or, at least the actors who played them.

Ashton Kutcher and Danny Masterson star in Netflix's new sitcom, out April 1, making it an unofficial but long-awaited That '70s Show reunion. Though, Masterson is quick to point out it's not the whole gang.

"There were a lot of cast members in That '70s Show, but there's only two of us here," he told ET before a special screening of the series. "So, we are reunited as Starsky and Hutch might do, but, I don't know if it's a full show reunion. But Wilmer is here tonight, so maybe we can get him on our show too!"

Wilmer Valderrama, aka Fez, did indeed step out to support his former co-stars, as did Kutcher's wife, Mila Kunis, who played Jackie. Missing from the reunion was Laura Prepon (Donna), though Masterson said she had a good excuse.

"Laura's in Africa, otherwise she would be here," he revealed. "But she sent me texts of kisses and such."

As for whether more That '70s Show cast members will join Kutcher and Masterson onscreen, Kutcher says there's a "high likelihood" that will happen -- including Kunis, who guest-starred on his last series, Two and a Half Men.

"Nothing's out of the question," he teased.

Prepon may be the easiest to lock down for a cameo, as she's already on another Netflix series, Orange Is the New Black.

"It's all part of the Netflix family," Kutcher added, though he wasn't too sure there could be an official crossover between the shows. "I don't know that this would cross over that well. We could actually be the prequel to how her character ended up in prison!"

Kutcher and Masterson also revealed that their daughters are already best friends! Find out what they exclusively told ET about the little "terrors" in the video below.
