According to Variety, the two stars will be joined on set by Vanessa Hudgens, Charles Melton and Alexander Ludwig, who will play members of a "modern, highly specialized police unit that collides with the old school Bad Boys when a new threat emerges in Miami."
The sequel is tentatively titled Bad Boys 4 Life, and is slated to release in January 2020.
The original Bad Boys was released in 1995 and helped skyrocket the careers of Smith and Lawrence, grossing US $141.4 million worldwide on a mere $19 million budget. It also marked the feature directorial debut of Michael Bay.
Bay returned for the 2003 sequel Bad Boys II, which earned US $273.4 million worldwide from a much larger $130 million budget.
