Hilary took advantage of the crisp Fall weather by wearing a sweater and a hat, while Jason showed off his muscles in a t-shirt and denim jacket.
The outing comes four months after Hilary was spotted kissing Mike during a friendly meet-up with their son in May.
She told Pridesource that “It was really fun for me for a minute.
Hilary Duff’s boyfriend is officially known, ever since the star posted a photo of her kissing Jason Walsh on Instagram.
I think that I was in a very successful marriage for a long time. But marriage is sacred and marriage is not for everyone. “As much as I was ready and excited, you're like, ' Oh, next step: We get married.' That's kind of the traditional person I'm talking about that's inside of me, or however I was raised. But that doesn’t mean she is giving up on monogamy. "I have dreams and aspirations, but I've never really been one of those people who has set dates: ' I'm this age, so this, this and this needs to happen.' That's just not really realistic. My life is very full, so I feel blessed and lucky,” she enthused.
At one point the couple had apparently tried to rekindle their romance but it was Hilary who finally filed for divorce in February 2015.
Hilary remains on good terms with her ex, especially as they have a child together, she revealed that they are good friends and have a good relationship which enables them to create a loving and comfortable atmosphere for Luca.
Hilary was quite open about the fact that she was keen to start dating again as she even revealed that she had signed up to Tinder.
Rumors swirled back in June that Hilary Duff was quietly dating her trainer, Jason Walsh, and on Saturday, the pair seemed to confirm their romance when they were spotted holding hands in New York City.
The Younger actress, who shares son Luca, 4, with ex-husband Mike Comrie, looked relaxed during her stroll with Jason around the city's So Ho neighborhood.
