Hollywood “It” girl Scarlett Johansson put on her running shoes and sweats to launch REEBOK’s latest celebrity athletic line at Nordstrom department stores.

The new “Scarlett ‘Hearts’ Rbk” collection comes as a stylish collaboration between the “world’s sexiest woman” (in a poll of readers by FHM magazine) and the active wear brand.

“I had thought about doing a cotton line for a while and then was coincidentally approached by Reebok to do a casual lifestyle collection,” she said, wearing a blue sweat top with pretty heart cutouts in back and black leggings. “It seemed like the perfect combination.”

The Scarlett “Hearts” Rbk collection, in stores now, was inspired by the decade that launched aerobics headbands and scrunchy socks. 

The line features items such as; candy-colored racer tanks, hooded sweatshirt tunics, 1980s-inspired track jackets and baseball raglans with heart embossing, as well as a collection of retro looking athletic shoes in neon colors. Even the running shoes have an old-school feel with their blue and red vinyl sides and yellow or white stripes.

The “Black Dahlia” and “Match Point” star said she personally pawed through jackets and sneakers at vintage store racks to find the colors and styles she was looking for.

“We did a lot of shopping. I wanted to feel like I was designing for my friends.”

The shoes and track jackets retail for $89.99 while racerback tanks and tunics range from $39.99 to $99.99. So far, the feedback has been … shall we say, ‘hearty’?
