Wilmer Valderrama hates when people lie

Wilmer shared: "My biggest pet peeve is when people lie. I also can't stand it when someone chews with their mouth open."

The actor - who previously dated pop star Demi Lovato from 2010 until 2016 - also revealed how the late actor Robin Williams continues to influence his outlook on life.

Speaking to Us Weekly, Wilmer explained: "The greatest advice I've ever received was from Robin Williams: 'Never forget. And always remember ... It's supposed to be fun.'"

Wilmer made the comments shortly after he revealed the 'That '70s Show' cast have discussed a movie reunion.

The actor - who played Fez on the hit sitcom alongside Mila Kunis, Ashton Kutcher, Laura Prepon, Danny Masterson and Topher Grace - confirmed that he and his former cast mates are "up for" bringing the popular show to the big screen.

He said: "We have had a conversation about a 'That '70s Movie'. And we have had a conversation about, 'Can this be real? Can it happen?' We're up for it.

"There is nothing in the works right now, and I believe all of us are a little too busy right now to make it happen."

But Wilmer admitted the cast would love to reunite on set one more time - although reprising his role as Fez for a potential film could present some problems.

He added: "Everybody is excited to hang out together again on set, that's one fact. I will probably have to re-learn how to say my accent. I will probably have to re-learn how to talk like a freak."
