Scarlett Johansson and Reebok are partnering up on a new project.

Details are very sketchy at the moment while the althetic company keep the details quiet. At least until July 25, when their collaborative plans will be unveiled at a New York fete.

No doubt Scarlett will be modeling whatever she is collaborating on with Reebok though.

Already a spokesmodel for L’OrÃ©al, she is also the face of Calvin Klein fragrance, Eternity Moment. Throw in her stint as a model in Louis Vuitton’s Fall 2004 advertising campaign, at the grand old age of 21, she’s done quite a lot.
