Although they have managed to keep their romance under wraps, it seems as though Ashton Kutcher and Mila Kunis have finally made the decision to officially go public. The celebrity couple was spotted kissing and holding hands in New York City on Tuesday.

Daily Mail reports that the couple was on a trek by foot from Greenwich Village to Central Park.

Regularly stopping at crosswalks, the "Two And A Half Men" was seen sweeping the 29-year-old in for a kiss at every opportune moment. Kunis was periodically seen gazing up at Kutcher adoringly as they bonded together.

Upon their Central Park arrival, the actress placed her hands on Kutcher's face and planted a passionate kiss while he multi-tasked on his phone.

Kunis appeared to have recently awoken as she sported tousled hair, a loose fitting sweater, gray sweatpants and sneakers. Kutcher, 34, was equally dressed wearing a white t-shirt, baseball cap and sneakers as well.

The newbie pair had become friends over a decade ago after co-starring on the hit sitcom "That '70s Show" from 1998 to 2006. They were first romantically linked together in April, which was soon after the demise of Kutcher's marriage to actress Demi Moore.

Kunis came out of an eight year relationship with "Home Alone" actor Macauley Culkin in January.

In the August edition of the British publication Elle, she had initially denied the rumors over her relationship with Kutcher.

"Listen, [Ashton and I] 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."

Contrary to Kunis' remarks, it seems as though things are getting serious between her and Kutcher. A friend of the couple has stated to Now Magazine that Mila and Ashton have recently started looking in to adopt an abandoned dog together.

"They have their hearts set on a big dog - either a golden retriever or a Labrador," stated the friend.
