The other casting is rapper Lil Wayne, who is currently in negotiations to join the fourth installment in the popular car franchise.

Fans of TV, especially CBS’ Navy NCIS, will probably recall Liza Lapira (pictured, below) as Special Agent Michelle Lee on the show. The Filipino actress was also recently in the surprise hit “21″, about MIT students who use their skills to break Vegas casinos.

“Fast and Furious 4” is due out in 2009.
