They're Instagram official!
There's now some serious visual proof that Hilary Duff is dating Jason Walsh.
The "Younger" star, 29, posted a sexy photo of herself kissing her hunky personal trainer on Instagram on Oct. 16, captioning it simply, "Date night with J ❤️."
The move comes just a few weeks after Hilary -- whose divorce from former hockey pro Mike Comrie, the father of her 4-year-old-son Luca, was finalized in January -- was put on the spot during a television show appearance and tentatively confirmed the romance.
In a late September interview with FOX 5's "Good Day New York," the host brought up pictures of the actress and Jason walking around New York City earlier this year and asked if Hilary had found some "like" in her life.
"We have," Hilary said, blushing. "We've known each other for a really long time and he's a great guy and we have a lot of fun together. It's nice to have that excitement in my life."
"Rise Nation" founder Jason is the celebrity personal trainer who helped Matt Damon transform his body for "Jason Bourne" and Bradley Cooper gain 40 pounds for "American Sniper."
He's also the guy who showed John Krasinski how to get ripped for "13 Hours" and the upcoming "Jack Ryan" Amazon series.
Last year, Hilary admitted that she was on Tinder to try to find dates.
"I was sitting with my friends one night at the house and we were joking around," she told the "Valentine in the Morning" show in April 2015. "In my life, I have always had really serious boyfriends. I've always met people through work and I have never been on a blind date. And so, what's the worst that could happen? I think I'm talking to probably about nine guys right now."
When asked what she was looking for in a guy, she said she hates beefcake photos. "I don't want to see a shirtless mirror selfie. That's instantly a left."
