Ashton Kutcher & Mila Kunis: A Match Made in Chicago Bears Tees

Ashton Kutcher and Mila Kunis are a perfect match. Literally.

The co-stars-turned-couple sported jeans and matching Chicago Bears T-shirts on a stroll in New York City Sunday. Kutcher put his arm around Kunis as they walked. They met on the set of "That '70s Show;" she's since been recognized for "Forgetting Sarah Marshall" and "Black Swan."

The matching tees came the day after the pair had a romantic dinner at Spasso in New York where they were seen holding hands and kissing.

Kunis and Kutcher were first spotted as more than friends at the July 26 wrap party for Kutcher's new film, "Jobs." In August, the pair jet-setted to Bali where they reportedly spent a week at a five-star resort. The former co-stars were snapped holding hands as they walked through the airport.

Kunis told the August issue of Elle UK that she was "totally single."

"Listen, we hang out. We've known each other for 15 years. We have mutual friends. We're comfortable with one another. That's it! There's no crazy love story, nothing more," she told the mag.

But the former stars of "That 70s Show" were spotted sharing a passionate kiss in New York City's Central Park Sept 17.

On "That 70s Show," their characters, Kelso and Jackie, dated.
