Wilmer Valderrama, who worked in "That '70s Show" as Fez, has opened up about his potential appearance in the upcoming Netflix spin-off "That '90s Show."

"I'm a little busy right now, but I support them so much," the 42-year-old actor told TV Insider on Sunday. "I'm rooting for them. I wish them nothing but the best."

However, the actor confirmed that he will be keeping the door open for his return to the sitcom's spin-off. "If the timing is right, I'd never say no," he said.

"That '70s Show" sitcom was released on Aug. 23, 1998, and the last episode was released on May 18, 2006. The sitcom ran for eight seasons, featuring Eric Forman (Topher Grace), Donna Pinciotti (Laura Prepon), Jackie Burkhart (Mila Kunis), Steven Hyde (Danny Masterson) and Michael Kelso (Ashton Kutcher).

The spin-off will revolve around Eric and Donna's daughter Leia (played by Callie Haverda). It will also star Kurtwood Smith, Debra Jo Rupp, Maxwell Acee Donovan, Sam Morelos, Ashley Aufderheide and Mace Coronel.

Fans are expecting Grace, Prepon, Kunis and Kutcher to return for the spin-off. However, no official announcement has been made yet.

Valderrama will be next seen in the TV series "Zorro," where he will play a character named Don Diego de la Vega aka. Zorro. It will be based on the 1950 Disney series of the same name. The series is currently under pre-production.

Moreover, the actor has been a regular on the popular drama series "NCIS" since 2016.

He lent his voice to the popular animated movie "Encanto" and its animated musical sequel, "Encanto Sing-Along," which was released last month. Valderrama also appeared in a music video, titled "Holy," alongside Justin Bieber and Chance the Rapper.

On the personal front, Valderrama got engaged to model and social media influencer Amanda Pacheco in January 2020. The couple welcomed a baby girl in February last year.
