Katie Holmes takes major step in romance with boyfriend Jason Bard Yarmosky

Katie Holmes and her boyfriend Jason Bard Yarmosky are Instagram-official.

The actress posted a sweet Instagram tribute to her beau on Tuesday.

“Happy Birthday to the best of the best…❤️ @jasonbardyarmosky,” Holmes captioned a sweet photo of her and Yarmosky embracing.

The joint post also included a pic of the artist’s birthday cake.

Last month, the duo soft-launched their relationship on social media.

At the time, the “Dawson’s Creek” alum re-shared multiple Instagram Stories posted by Yarmosky, including a sweet photo he seemingly snapped of her.

Rumors first swirled that the two were dating in July when an eyewitness told People they were holding hands at a Hamptons movie screening.

“He was whispering in her ear, and she was laughing, they seemed very easy together and there was a smile on her face all night,” the insider shared.

TMZ reported that the pair first met at a Tribeca Festival dinner in New York City in June.

Relationship rumors between Holmes, 47, and Yarmosky, 39, intensified after Page Six obtained photos of the pair looking smitten during a dinner date in NYC later in July.

In the snaps, they couldn’t keep their hands off each other, wrapping their arms around each other as they strolled through the city.

That same month, an insider exclusively told us that despite the pair’s closeness, Holmes wasn’t ready to introduce him to her daughter, Suri, whom she share’s with ex-husband Tom Cruise.

“Things are still pretty new between Katie and Jason, and they’re intentionally taking it slow. They haven’t been introduced to other’s families or done any of that yet,” the source told us.

“Right now, they’re just enjoying spending time together,” the insider continued.

“There haven’t been any major steps in the relationship yet, they’re still in the dating phase for now. They’re happy taking things as they come and seeing where it goes.”
