Lethal Weapon

FOX | 8:00 pm

Music star Jason Derulo already was a presence on Fox as a judge on "So You Think You Can Dance," and he has an acting role in "Surf N Turf," guest-starring as a boxer whose Hollywood party is disrupted by gunfire. The resulting investigation clues Riggs and Murtaugh (Clayne Crawford, Damon Wayans Sr.) into a gun-running operation. Riggs’ interest in the case is stoked by a pregnant woman who reminds him of his late wife.
