Jacqueline Carrizosa is a former Navy gunner's mate and search and rescue swimmer. She's the one who helped Rihanna look totally legit shooting the big guns in Battleship.
"She was the first famous person I ever met," says Jacqueline of her headline-magnet student. "I didn't know what to expect. [She made me realize] that everyone can be cool."

What did Jacqueline think of the final product? "I was super stoked watching it!" she says.
