The pair shared the screen in three Rush Hour flicks - in 1998, 2001 and 2007 - and although there has been a lot of speculation about a fourth being made, things looked uncertain after Jackie announced earlier this year that he was done with action films, saying that he wasn't young any more and that the world was already "too violent".
But Chris has now told E! News he is crossing his fingers that another sequel is made.
He said: "It's going to be a lot of fun. I hope it happens. We need to do one more."
The 41-year-old actor went on: "I love working with Jackie, being around Jackie. Stuff just happens when we're together."
In May, Jackie announced that his movie Chinese Zodiac would be his last action film.
"I tell you, I'm not young any more. I'm really, really tired," said the 58-year-old.
"And the world is too violent right now. It's a dilemma - I like action but I don't like violence."
