Scarlett Johansson refuses to be left behind.

With other popular actresses cashing in on their celebrity by inking lucrative deals and endorsements with major brand names -- Elizabeth Hurley just signed with Jordache -- Miss Johansson has agreed to team up with Reebok for a fashion project.

Next spring, the sneaker giant will launch Scarlett "Hearts" Rbk, a line of athletic-inspired footwear and fashion-forward apparel. Miss Johansson also will model the head-to-toe looks in a global multimedia advertising campaign.

Reebok won't say how much the 21-year-old film star is being paid.

Reaction has been swift. At idontlikeyouinthatway.com/, one blogger commented, "It's nice to see a woman with curves being recognized as sexy" while another declared: "I wish she would stick to acting, but I guess the money is that tempting."
