Bobby Flay and Brooke Williamson are ringing in the new year with a relationship milestone!
The Food Network stars hosted their first New Year's Eve celebration together at Flay's new barn in the Hamptons. Williamson, 47, took to Instagram to document the fun-filled festivities in a Jan. 1 post and share a look inside the stunning space.
A source tells PEOPLE that Flay's new property is a "beautiful" 240-year-old barn that he had "relocated and reconstructed" from Sullivan County, N.Y. to the Hamptons hamlet of Amagansett, making it the perfect spot for the couple to ring in the new year. The celebrity chef, 61, is working on creating a full outdoor kitchen at the future event space as well, the insider adds.
Williamson offered a peek inside in her post, beginning with the massive glowing fireplace that the couple posed next to in the first slide. They are seen sharing a sweet embrace as they stand in front of large glass doors that lead out to a patio.
Another clip included in the post shows the couple dancing in a long hallway equipped with large windows and wooden ceilings.
Williamson dons a sparkling gold dress and a black headband with two stars on it that say, "Happy New Year," while Flay keeps it simple with a white button down and black tie.
It's no surprise that the couple celebrated the holiday by cooking a feast for their guests in the massive kitchen. One time lapse-style video shows the pair hard at work as they prepare multiple dishes for the party.
In addition to snapping a sweet selfie together, the pair also leaned in for a kiss in the last slide. Flay has his arm wrapped around his girlfriend's waist as they pose in front of the fireplace together.
A statement light fixture can be seen hanging above them, while exposed wooden beams peek out in the background.
Flay and Williamson first went public with their romance in March, and have since been documenting aspects of their relationship on social media.
Last month, Flay wrote on his Instagram Stories that one of his New Year's resolutions for 2026 involved his relationship with Williamson: "To be the best boyfriend possible to Brooke and the most important Dad to Sophie," he wrote in the Dec. 16 post.
Flay is dad to daughter Sophie, 29, from his marriage to Kate Connelly, while Williamson has a son, Hudson, from her previous marriage to Nick Roberts.
In June, Flay opened up to PEOPLE about their relationship and what it's like to work together on Bobby's Triple Threat.
"I love working with Brooke," he told PEOPLE at the time. "We have a lot in common. We're very lucky. We're both chefs. We both have kids. We're both parents."
He added, "And one of the things I really like about being in a relationship with Brooke is that she's great to bounce things off of. Like we ask each other's opinion about things that we're doing food wise or restaurant wise or business wise, all the time. So it's really nice to have kind of a best friend that you're dating that can also be helpful answering the questions that you have."
